Abstract
The paper rehearses arguments for and
against the prediction of massive technological unemployment. The main argument
in favor is that robots are entering a large number of industries, making more
expensive human labor redundant. The main argument against the prediction is
that for two hundred years we have seen a massive increase in productivity with
no long term structural unemployment caused by automation. The paper attempts
to move past this argumentative impasse by asking what humans contribute to the
supply side of the economy. Historically, humans have contributed muscle and
brains to production but we are now being outcompeted by machinery, in both
areas, in many jobs. It is argued that this supports the conjecture that
massive unemployment is a likely result. It is also argued that a basic income
guarantee is a minimal remedial measure to mitigate the worst effects of
technological unemployment.
1. Introductory
I consider myself a disciple of Chicken
Little, for I too believe the sky is falling: the unemployment sky, that is.
Chicken Little’s conjecture is that prospective developments in computers and
robotics will result in an age with greatly reduced demand for human labor
compared with the present. However, I am not a follower of King Ludd (leader of
the Luddites). I believe the era of reduced need for human labor will be a
wondrous thing for humanity. On the horizon is an age where we might work
because we want to work, not because we must work; an age where human labor is
like the labor we devoted to our hobbies, motivated by joy and self-actualization.
It will be very unlike our current threat-economy where fear of starvation,
homelessness and death is a stick to ensure compliance by the masses to the
imperative to work.
The main obstacle I see is getting from
here to there. The change will be gradual. At some point, the labor of some but
not all will be entirely optional. Or to put the point negatively, the
threat-economy faces a paradox: the threat-economy says everyone must work but
the threat-economy will not generate enough jobs for everyone, so the work of
some will become redundant. How are these people to manage in an economy metamorphosing
from the old to the new? A basic income guarantee (BIG) is the most attractive
policy to help transition from the old to the new. I advocate instituting a BIG
today to help us transition to a future so bright we will need robotically
produced shades.
As a disciple, it is incumbent upon me to
deal with an embarrassing problem: the master has been wrong for a solid two
hundred years running. After all, the prediction that technological
developments will lead to massive unemployment has been made since at least the
turn of the 19th century, and at least over the long term, the
prediction has proven false. The question, “Isn’t two hundred years of failure
enough?” deserves an answer. The aim of this essay is to provide an answer. While
I concede Chicken Little’s case doesn’t look promising, at least initially, I
hope to show that if we dig a little deeper, we can see why there are good
reasons for siding with Chicken Little despite two hundred years of failure.
2. Technological Unemployment
One way to see the threat to employment
from robotics is to think about all the jobs presently done by humans that
could soon be done by robots. To see this, let’s fast forward ten or twenty
years and imagine you need to do a little shopping. You go to your local
Walmart and pick up a few groceries and other household items. On the way to
your office you realize you forgot to buy an electric razor, so you order one
through Amazon on your cellphone. Your trip to the office is to pick up a book
you are supposed to review. When you get home, you are not surprised to see
that the razor from Amazon actually beat you to your doorstep. As you sit down
to dinner with your clean shaven face to read your new book, you marvel that in
all likelihood, all the products you are using were untouched by human hands
other than your own.
How is this possible? The answer, of
course, is robotics. The book you are to review was run off and bound by the
licensed printer at your university. Yes, you could have received an electronic
version right to your tablet, but you are old fashioned: you still like the
feel of a paper book in your hands. Hence you had to use one of the few
printing and binding machines that you know of: the one at your university. The
razor was made at an entirely robotic factory and shipped robotically to an
Amazon distribution center. When your order was placed, it was robotically
packaged and sent out in a small robotically driven helicopter, small enough to
drop the package right at your doorstep.
Your trip to Walmart also did not require
human touch (other than yours). Gone are the days of waiting in line to have
your items scanned and bagged. As soon as you put an item in your shopping cart,
the embedded RFID tag was read and the item automatically charged to your
account. Gone too are the small army of human shelf stockers. This job is now
done robotically. Robots are also in use at every step in the distribution and
production sequence. Robots packed and drove the food to your local Walmart.
Robots also were used to grow the food on the farm. Then they were packed and
shipped robotically as well.
I expect two quite different reactions to
this little description of consumption in the year 2024 or 2034: some will
think it is wildly implausible because it attributes too much to robotic
developments; others will find it wildly implausible because it attributes too
little to robotic development. The latter reaction is probably closer to the
mark; but only the former is inconsistent with what is argued here, so we shall
focus on it.
What may be unnerving for those who do not
follow robotic development closely is not how much extrapolation from our current
technology is required, but how little. Some of this is already a reality. Part
of our little story involved print-on-demand technology. But print-on-demand
robots are already available. By 2024, this will be considered ancient
technology.
The idea that the electric razor might
reach your hand untouched by any other human is only a small extrapolation from
current technology. Recently, Philips Electronics opened a factory in the Dutch
countryside that uses 128 robots and 1/10 the human labor as a counterpart
factory in China (Markoff, 2012). The robots work with greater acuity and
dexterity than is possible for an unaided human, e.g., one robot bends a
connector wire in three places, and guided by video camera, slips the bent wire
into holes too small for the human eye to see (Markoff, 2012). The robots are
able to do such incredible feats at such a rapid rate that the robots
themselves must be enclosed in glass cages: their rapid speed is a danger to
the few humans working in the factory. Of course, the robots are capable of
working 365 days a year, 24 hours a day. The new factory has made obsolete the
hundreds of Chinese workers who assemble razors in China the old way, using
human labor.
Not only is manufacturing being
revolutionized by robotic workers, but the same is happening in the shipping
and receiving industry. We are on the cusp of being able to get inventory from
the factory to the warehouse robotically. In some advanced warehouses, Kiva
robots are directed by a computer program to select inventory from the
warehouse shelves and bring it to human workers who actually place the items
into boxes for shipping. On the transportation end, Google has software for
driverless cars: vehicles that can drive themselves on busy roads. Of course,
legal restrictions still require a human driver capable of taking over the
wheel, but the software is already so good that experimental vehicles have gone
hundreds of thousands of miles without any human intervention. The safety
record of this software already exceeds that of the average human driver. It is
not hard to imagine that human driven vehicles may be illegal in twenty years,
only because they are so dangerous in comparison to robotically driven vehicles
Thus, it is only the barest extrapolation beyond today’s technology to imagine
robots packing orders at the factory, driverless trucks shuttling inventory
between factory and warehouse, and robots packing and driving orders straight
to the doors of customers. Amazon recently demonstrated a helicopter delivery drone
that could potentially make 30 minute deliveries possible, with the prediction
by its CEO, Jeff Bezos, that the technology could be deployed within five years
(Lee, 2013).
An obvious analogy here is the great
reduction in the workforce, as a percentage of the population, devoted to
agriculture. In 1790, there were about 3.5 million farmers, 90% of the
population, while farm workers now make up 1.6% of the population with 5
million workers (Growing a Nation, 2005). Poignantly, even this small residual
workforce will be replaced in large measure by “farmbots.” Small prototypes
being tested in the field do such things as plant seeds, pull weeds and harvest
in swarms. Although they are not ready for prime time at the present, it is
already possible for robots to plant, maintain and harvest fruits in the
laboratory. In all likelihood, in twenty years, robots will greatly outnumber
humans on farms in the U.S. Agriculture hasn’t seen the last reduction in its
workforce (Sager, 2013; Sofge, 2009).
Not only will we see a radical reduction in
the need for human employment in manufacturing, distribution, transportation
and agriculture, but in more “cerebral” professions as well. There are medical
programs that outperform even experienced physicians in diagnosing disease
(Khosla, 2102). Surgical robots are also being developed. In both cases, the
physician and the surgeon are not completely replaced, but it is easy to
anticipate the need for both on a per capita basis might drop dramatically. For
example, up to 60% of visits to family physicians are for upper respiratory infections
that can be easily diagnosed with a computer program (Gonzales, Malone,
Maselli, & Sande, 2001). The point again is that the claim is not that
either profession is going to be completely replaced by robotics in the next
twenty years, it is, rather, that robotics will increase the efficiency of
physicians and surgeons such that fewer will be necessary per capita. A title
of a recent CNN article summarizes the trend: “Technology will replace 80% of
what doctors do” (Khosla, 2102).
It seems that hardly a week goes by when
there is not some headline about robotics taking jobs. Almost to the day when I
had finished a draft of this paper, a Wall
Street Journal headline appeared with this intriguing title, “Robots vs.
Anesthesiologists: J&J New Sedation Machine Promises Cheaper Colonoscopies;
Doctors Fight Back”(Rockoff, 2013).
About a billion a year is spent on sedating patients for colonoscopies. The
robotic anesthesiologist developed by Johnson & Johnson promises to take
over much of the labor of anesthesiologists. Physicians actually performing the
colonoscopy typically charge in the $200-$400 range for each procedure.
Anesthesiologists charge an additional $600-$2,000 on top of that. The robotic
anesthesiologist, now approved by the FDA, would work for a fraction of the
cost: $150 or so, per operation.
Medicine is not the only high profile
profession under siege: there are computer programs operating today that can
perform legal research faster and more effectively than well-trained lawyers
(Krugman, 2011). We need not imagine a future where robotic lawyers stand up in
court to give an eloquent defense of the accused to see that the need for human
labor in the legal profession will decrease.
The so-called “oldest profession” should
also worry about the reduced need for human labor. Sexbots are available now
with several different “personalities,” capable of performing a number of
different sexual acts. The reason they haven’t penetrated, as it were, the
market further, is due at least in part to their price: they typically retail
in the neighborhood of $10,000. As the price drops, there is every reason to
suppose sexbots and other robots will replace even more human labor (Levy,
2011).
Part of why the robot revolution is still invisible
to many, despite much recent press, is that we are still suffering a hangover
from earlier expectations. There was a lot of optimism in the 1960s that
general purpose humanoid robots might be a reality in the 1980s. The promise,
obviously, was not fulfilled. Instead, what we have are far more limited
special-purpose robots. Presently, robots are designed for very specific tasks,
e.g., most of the robots sold for floor cleaning are specialized in terms of
whether they vacuum or wash the floor. The idea that we would have a general
purpose house servant like “Rosie” from the Jetsons is a long way off. Still,
once our expectations have been retrained, we can see why the robot revolution
is inevitable: robots are getting incrementally cheaper and better every year.
Robotic vacuum cleaners like Roomba have
vastly improved in the last decade. When they first reached the mass market,
they were designed to clean a single room, prone to falling down stairs,
getting stuck in corners, and they needed to be recharged by humans. Now, many
can vacuum a whole house unaided by humans. When the batteries run low, the
robots return to their “feeding stations” where they recharge. They are by no
means perfect but certainly much better at vacuuming than your average
teenager. They also work cheaper and do not complain.
Another example of robotic progress is
Baxter from Rethink Robotics. Baxter is an industrial robot designed by Rodney
Brooks, inventor of the Roomba robot. Consider cost first: Unimate is usually
credited with the installation of the first industrial robot in 1961 (Roy,
2014). The robotic arm worked at a General Motors factory with hot die cast
metal sorting and stacking. Unimate sold the robot at a loss: it cost $65 million
to make and Unimate sold it for a paltry $18 million. Baxter costs more than a
1,000 times less, retailing at $22,000. Even compared to many of its
contemporary competitors, Baxter is a giant leap forward. Often the price of
the robot is a fraction of the total cost of operation. For example, a typical
industrial robot that costs $100,000 at present might use an additional
$400,000 in labor fees to have programmers write and debug code to instruct the
robot how to perform its task. Baxter, in contrast, can be trained by factory
workers: it is simply a matter of guiding Baxter’s arm to show it what needs to
be done. Baxter learns by doing rather than having new code input. This makes
the lifetime cost of Baxter an order of magnitude cheaper
than many of its competitors ($22,000 versus $500,000). Robots like Baxter will
revolutionize industrial production.
As mentioned above, the robot revolution is
being spearheaded by specific-purpose built machines. And because of this,
there are very few who are able to see the revolution in all its clarity because it
requires knowledge of developments in a number of specialized domains. For
example, when a reporter asked Rodney Brooks, inventor of both the
aforementioned Roomba and Baxter robots,
how long it might be before robots could replace McDonald’s workers, his
response was very telling: According to Kevin Kelley, Brooks claimed that “it
might be 30 years before robots will cook for
us” (Kelly, 2012). His reasoning for this prediction is also
interesting: “In a fast food place you’re not
doing the same task very long. You’re always changing things on the fly, so you
need special solutions. We are not trying to sell a specific solution” (Kelly, 2012). I can’t help but wonder whether
Brooks has ever worked at a fast food restaurant. As a former McDonald’s
employee, I can attest to the repetitive nature of the work.
I would describe working there in exactly the opposite way: you do the same
task for a very long time with little variation in the routine at each station. Interestingly, there is already a robotic hamburger maker
available from Momentum Machines (Murray, 2013). It will cook up to 360
hamburgers an hour, plus cut fresh tomatoes, lettuce and pickles. Or consider
Kura, a sushi restaurant chain in Japan that uses robotics to lower its labor
costs (Chan, 2010). The fact that a world class roboticist like Rodney Brooks
has underestimated the robotic revolution is revealing. The reality is that we
are almost at a tipping point where robots are cheaper even in an industry
known for its low cost labor.
Indeed, what is disturbing is that even in
China, with its notorious low wages and harsh working conditions, there is a
move to robotics. The Chairman of Hon Hai (also known as Foxcon), manufacturers
of Apple’s IPhone and other electronic devices, announced a few years back that
the company’s goal is to have a million industrial robots in use by 2014
(Wagstaff, 2011). The plan has hit some snags but is still proceeding at an
aggressive pace (Perez, 2012). Some analysts suggest the price of robots is
still too high for it to make economic sense for Hon Hai, suggesting that the
price per robot would have to fall to $25,000 from their current $50,000 to
$200,000 level. Interestingly, this is the price of the aforementioned Baxter.
So, again we are reaching a tipping point where even in a low wage country like
China, it makes economic sense to replace human workers with robots. Indeed, as
we noted, Philips Electronics has already found it more economical to set up a
robotic factory in Europe than have electric razors made in China with cheap
labor and then shipped to Europe.
The logic behind this move is explained by
Hon Hai Chairman Terry Gou: "Hon Hai has a workforce of over one million
worldwide and as human beings are also animals, to manage one million
animals gives me a headache”. Terry Gou added that he wanted to learn from Chin
Shih-chien, director of the Taipei Zoo, regarding how animals should be
managed. Whether we find this offensive or not, it is hard to deny the logic of
his thinking from a ruthless business perspective. Humans are expensive
machines to run and maintain. The working conditions of Hon Hai regularly make
the headlines because, as noted, they are the major manufacturer of Apple
products. It is alleged that the working conditions at Hon Hai are terrible and
that there have been a number of suicides as a result. Whether this is true or
not, it is clear that negative publicity is not something Hon Hai desires. Even
if humans could compete with robots in terms of work produced per hour, the
extra “headaches” of managing “animals” is surely going to tip the scales in
favor of robots. Focusing just on the economics of the issue, if the price of
robot and human labor is even, then robots are leaving humans in the dust.
3. The Economists Versus Chicken Little
It can’t be stressed enough that the
argument is not that machines will
completely replace all human labor. This may come to pass one day. (However, there
are good moral reasons why it would be wrong for robots to replace humans in all occupations (Walker,
2006).) Long before this transpires, robots will partially replace humans in
the workforce. This is the point I mentioned above where we are between two
economies: between the threat-economy and the non-threat-economy. As long as
the economy does not produce enough jobs for everyone to stave off the usual
threats from the threat-economy—starvation, homelessness, death—Chicken Little
is right. So, the argument is the relatively modest claim that robots will reduce the need for human labor below
full employment.
It may help to put some numbers to these
claims. The height of unemployment during the great recession of 2008-2009 was
about 9.9% by 2010 (Bureau of Labor Statistics, 2010). If technological unemployment
is occurring, within ten years the rate of unemployment will consistently be
higher than this and it will continue to grow. In other words, the reason for
the higher unemployment rate will be due not to the cyclical nature of markets
or subprime mortgages, but because of huge increases in automation.
To this conjecture, it is often objected
that economies have also found jobs for displaced workers in the past; for
example, when backhoes automated the work previously performed by hundreds of
workers on a single worksite with shovels, many laboring jobs were lost. But
economic growth spurred new employment opportunities for the displaced
laborers, including work in factories making backhoes, backhoe mechanics and
backhoe salespersons.
Pressing the objection, it might be
suggested that the analysis here is mere Luddism. The Luddites (1811-1817)
reacted against the mechanized machinery of the industrial revolution. Skilled
artisans in the textile industry were replaced by machinery and less skilled
labor was required to operate the machinery. In response, the Luddites wrecked
machinery, killed capitalists and battled with the British army.
In hindsight, it is easy to sympathize with
their plight, if not their prescription. These artisans had much to fear. It is
true that the economy as a whole benefited with the reduction of the price of
textiles, but most of these workers did not reap a commensurate reward. Their
jobs were permanently lost to automation and their particular skill set did not
position them well to compete in a new economy. Imagine their plight as all the
workers who put the requisite years in to learn their craft found out that
their skill was no longer needed and that they would have no way to look after
their families. At the micro level of the individual worker, this is very sad.
At the macro level, we can see the benefit to the entire economy.
The same thing that happened to textile
workers happened in many professions. The objection, then, can be summarized by
saying that the history of the modern world is one of workers made redundant by
machines. And each time workers are made redundant; disciples of Chicken Little
have suggested that the employment sky is falling. Each time the prediction of
massive unemployment as a permanent feature of the economy has proven false.
Yes, there is pain as the economy readjusts, but eventually workers find new
jobs; often in entirely new industries. This line of rebuttal to technological
unemployment is nicely summarized by the economist Alex Taborrok:
I am growing increasingly annoyed with
people who argue that the dark side of productivity growth is
unemployment. The Economist, which ought to know better, says we
are overproductive. CNN Money discusses the problem of
productivity, the President blames productivity growth for
unemployment. Even someone as sophisticated as Brad
DeLong writes “with productivity surging, it’s hard to be pessimistic
about GDP growth, but it’s easy to be pessimistic about unemployment” which
seems to suggest that if only productivity growth were lower, employment would
be higher.
And yet the “dark side” of productivity is
merely another form of the Luddite fallacy – the idea that new technology
destroys jobs. If the Luddite fallacy were true we would all be out of work because
productivity has been increasing for two centuries. Sure, some say, that may be
true in the long run but what about the short run? Even in the short run there
is no necessary connection between productivity growth and job loss. In the
computer industry, for example, productivity growth has led to falling prices
and a bigger not smaller industry. If demand is inelastic then productivity
growth can create short-term unemployment, especially at the level of the
industry experiencing the growth – less likely but not impossible is that
productivity growth leads to short-term economy-wide unemployment (Tabarrok,
2003).
I will refer to this objection as the
‘economists’ objection’ simply for ease of reference. I do not mean to suggest
that all economists endorse this idea, nor do I mean to suggest the idea is
proposed only by economists. Indeed, the belief that the economy will always
generate enough jobs seems to be well entrenched: every year I hear college
freshpersons make it with the same unflinching faith as economists like
Tabarrok.
Notice that the economists have the more
extreme position. They are committed to the idea that the economy will generate
full employment. Chicken Little wins if there is massive technological
unemployment or even just a little unemployment. The reason for this division
stems from the nature of the threat-economy. It says everyone ought to work (or
face starvation, homelessness and death). If robots take away enough employment
to make full employment impossible, then the paradoxical result emerges that
there is a demand for people to do the impossible. Therefore, as long as full
employment is not possible, the threat-economy will have to be reconceived to
remove the contradiction.
4. The Nature of the Debate Between Chicken Little and the Economists
Thus far I have merely rehearsed the
outlines of a familiar debate. It is easy to get the impression that we are at
an argumentative impasse. On the one hand, the case for Chicken Little is based
on the observation that computers and robotics are making inroads into so many
sectors of the economy: agriculture, mining, construction, manufacturing,
retail, professional services, teaching, health care, and food services to name
but a few. On the other hand, it is hard not to concede that the economists
have a very powerful case. Their argument in a nutshell is:
Premise
1: People wrongly claimed that automation will
result in massive technological unemployment from 1811-2014.
Conclusion: People who claim in 2014 that robots will result in massive technological
unemployment are wrong.
The seeming impasse is exacerbated by the
following problem: if we press economists to tell us where the new jobs will be
created for workers in displaced industries to move to, they will (rightly)
respond that it is generally impossible to foresee. The worker replaced by the
automated threshing machine had no inclination that his grandson would work as
an elevator operator. The elevator operator made redundant by automated
elevators had no idea that his granddaughter would be a cellphone engineer. This
makes the economists’ position hard to criticize because they claim that some
new but as yet unknown sectors of the economy will open up and employ workers
made redundant by automation. It is, of course, hard to argue against the
unknown.
Despite this seeming impasse, I believe the
case can be pressed against the economists. The first thing we should notice is
that the economists’ argument is an inductive argument based on the general
premise that the future will resemble the past. The general pattern of
reasoning is straight-forward enough. A reason to believe that the temperature
will dip below freezing next winter is that it has every other winter for as
long as humans have recorded temperature in these parts. A reason to think the
sun will rise tomorrow morning is that it has risen every morning since before
humans populated this planet. Similarly, the economists’ argument uses the same
inductive pattern: every time automation displaced workers in the past, new
jobs were found.
A crucial difference between inductive
arguments and deductive arguments is that it is possible to accept the premises
of an inductive argument but deny the conclusion, whereas with a deductive
argument, this is not possible. Consider this deductive argument:
Premise
1: People wrongly claimed that automation would
result in massive technological unemployment from 1811-2014.
Premise
2: If people wrongly claimed that automation would
result in massive technological unemployment from 1811-2014, then people who
claim in 2014 that robots will result in massive technological unemployment are
wrong.
Conclusion: People who claim in 2014 that robots will result in massive
technological unemployment are wrong.
If we accept premises 1 and 2, then we are
logically forced to accept the conclusion. With inductive arguments, it is
possible to accept the premises but deny the conclusion. Generally, however, we
need special reasons to deny the conclusion because denial of the conclusion of
an otherwise good inductive argument requires denying the idea that the future
will resemble the past. Suppose with the assistance of a time machine, you are
transported to Pompeii, August 23rd, AD 79. Someone tells you that fresh bread
will be available in the market the following day based on the fact that fresh
bread has been available in the market every day for over fifty years. This is
a very good inductive argument; but still you have reason to deny the
conclusion, that bread will be available tomorrow, even while accepting that it
has been available for the previous fifty years. Your knowledge that Vesuvius
will blow the next day gives you reason to think that the future will not be
like the past for the poor city of Pompeii.
I propose to take a similar line with the
economists’ argument. Although I think there are reasons to deny the premise,
we will assume for the sake of the argument that the premise, that automation
has not caused unemployment, is correct.
I will argue that there are reasons to think that the future will not resemble
the past with respect to employment. Accordingly, we have reason to deny the
conclusion of the economists’ argument.
5. The Good of Humans in an Economy
To see why the future will not resemble the
past, economically speaking, it will help to step back for a moment and ask
what role humans play in the economy. On the demand side, things are relatively
straightforward: humans are the primary consumers of the economic goods
produced in economies. On the supply side, our primary benefit is in the form
of labor. What we offer to the economy in terms of labor is helpfully
illustrated by comparison with horses:
There was a type of employee at the
beginning of the Industrial Revolution whose job and livelihood largely
vanished in the early twentieth century. This was the horse. The population of
the working horses actually peaked in England long after the Industrial
Revolution, in 1901, when 3.25 million were at work. Though they had been
replaced by rail for long-distance haulage and by steam engines for driving
machinery, they still plowed fields, hauled wagons and carriages short
distances, pulled boats on the canals, toiled in the pits, and carried armies
into battle. But the arrival of the internal combustion engine in the late nineteenth
century rapidly displaced these workers, so that by 1924 there were fewer than
two million. There was always a wage at which horses could have remained
employed. But that wage was so low it did not pay for their feed (Clark, 2008).
It is interesting to ask why new career
opportunities did not open up for horses after the invention of the combustion
engine. After all, if we are to believe that new job opportunities will open up
for humans in the robotic revolution, then surely capitalism should have found
jobs for horses after the internal combustion engine revolution. The unbridled
optimism of the economists seems to suggest full employment for horses too. So,
why did so many end up at the knackers? Why shouldn’t we predict the same thing
for human workers?
The answer is perhaps obvious: horses have
one main thing to offer the labor market, namely, their physical labor. As the
quote from Clarke indicates, it is not that physical labor is not valued in the
modern economy; it is simply that the internal combustion engine (or electrical
engine) can provide the same physical labor much more cheaply.
Horses also have some residual value in
terms of what we might call “nostalgia”. You can rent a horse and go for a
ride. Or you can take a ride on a horse-drawn sleigh or go on a carriage ride
through a park. No one pretends that these are the most efficient means to get
around. Some people just like being around horses, or enjoy fantasizing about a
bygone era when horses used to be the primary mode of transportation.
So, horses have two things to offer to the
economy: muscle and nostalgia. By and large, their muscle power is not
cost-effective in a modern economy. And the demand for horse nostalgia is not enough to keep horses
employed at the same rate they were in the early part of the twentieth century.
Humans have three things to offer the
economy: brains, muscles and nostalgia. History shows the inception of two
great transformations in the economy. The first, approximately 1800-1950, is
where human muscle power was replaced by machine power. Thus, starting in the
eighteenth century, there was a rapid rise in development of machinery to
replace human physical labor. First steam, and later, combustion and electrical
engines replaced human and animal labor. Take a simple example: A backhoe can
dig a hole for the foundation of a building in a day; a small army of humans
with shovels might take a month to do the same thing. In terms of energy output,
we can see why this is so: an average human might generate 1/10 of a horsepower
over an extended period of time, whereas a typical backhoe might be rated
around 100 hp. A backhoe operator, then, has at his disposal the equivalent
muscle power of 1,000 average human beings.
Perhaps nowhere is the replacement of human
physical labor with machine power more obvious than in agricultural production.
As noted above, at the turn of the eighteenth century in the U.S., about 90% of
the population was involved in agricultural production. A mere hundred years
later, this fell to 40% of the population. One such manual labor-saving device
was the introduction of threshing machinery in the late seventeenth and early
eighteenth century. Threshers separate wheat and other grain kernels from the
rest of the plant. Prior to the introduction of the threshing machine, this was
done through the use of a flail. A typical flail is two sticks of wood joined
by a piece of chain. A flail, then, looks much like a nunchaku weapon, often
seen in Kung Fu movies, although the sticks tended to be longer on a flail.
Workers would beat wheat and other grain crops in order to separate the “wheat
from the chaff.” This was extremely physically demanding and labor intensive.
With the introduction of the threshing machine, about 25% of the farming work
force was made redundant. Again, at the individual level, we should feel sorry
for those farm workers who were laid off and unable to find different work due
to the invention of the threshing machine. But at the social level, we can see
how automated farm machinery ultimately improved the lives of many: no longer
must 90% of the population work on farms with long hours, low pay and dangerous
working conditions.
The Second Great Transformation, 1950-2050,
is where computers and robots replace human minds in the economy. Humans can
still compete in the area of the mind, but as we have seen, this advantage is
dwindling. Robots that work in factories, advanced computers that drive cars in
busy traffic or make accurate medical diagnosis, or do effective law research,
all are making inroads into areas where humans once had a unique advantage.
There are two reasons for thinking that robots will continue to chip away at
our last great advantage in the labor pool. First, the cost of hardware for
robotic intelligence drops every year. This seems to be a consequence of
“Moore’s Law” which states that the number of transistors on integrated
circuits doubles every two years. In plain English, computer hardware gets more
powerful and cheaper every year. Secondly, gains in software can be distributed
virtually for free. A comparison with humans may serve to highlight the
difference. Teenagers are no better at vacuuming today than they were ten years
ago. It costs about the same to raise them, and each child has to be taught the
art of vacuuming. Compare that with robotic vacuums. If the computing power
necessary to run the robot’s brain cost $100 ten years ago, it now costs just
over $3. Programs for robotic cleaners have also improved in the intervening
period: robotic vacuum cleaners are less likely to fall down stairs, or get
stuck trying to vacuum up a sock. Each time programmers make an improvement, it
can be disseminated to current and future robots through a simple download. In
short, although we still have one great advantage in the labor pool, our minds,
our minds are not getting significantly better or cheaper, whereas robots are
improving on both scores.
We can see then why the past is not a
particularly good predictor of the future in the case of employment. With the First
Great Transformation humans were squeezed out of brawn type jobs but new
sectors opened up in brain type jobs. In other words, machines are encroaching
in the last area that we have a competitive edge. So, unlike the displacement
of labor during the First Great Transformation, there is no untapped category
for surplus human labor to migrate to.
A couple of caveats are in order. First,
the distinction between brawn and brain occupations is best thought of as lying
along a continuum with few (if any) pure forms of either. My job as a
philosophy professor is one of the clearer examples of a brain type job but
even my job requires human muscles. I must, for example, pass out and collect
student papers, carry books to class and so on. The brawn involved in my job is
fairly minimal: it is not enough to keep me physically fit by any stretch of
the imagination. Some of the purer forms of brawn jobs include rowing a galley
or threshing grain. Neither of these is a pure form of brawn as at least some
mental activity is necessary for each: following orders when to row, for
example. The claim about two great transformations, then, may be nuanced by
claiming that the First Great Transformation saw a mechanization of jobs that
tended to be on the brawn end of the spectrum and now we are seeing
mechanization of jobs more towards the brain end of the spectrum.
The second caveat is that humans will still
be employed in nostalgic functions. For example, one can take a ride in an
elevator in the Young-Quinlan Department Store operated by a human “elevator
operator”. Of course, at one time, elevators were not automated but run by
specially trained elevator operators. The few that are still in operation
appeal to nostalgia; it is certainly not cheaper to run an elevator with humans
as opposed to computers. As with horses, we should expect the demand for human
labor based on nostalgia will be pretty weak.
To summarize: the economists’ argument says
that new areas of the economy will develop to generate full employment. When Chicken
Little asks about these job creating sectors, the economists say that it is
hard to predict where the growth will come from. If it were easy to predict
where growth is going to come from, investment would be straightforward, but it
is not. The response to this is, even supposing new sectors of the economy open
up, their demand for human labor is likely to be very weak since these new
sectors too will be faced with the question of whether to employ robots or
humans. The cost advantage will lie with robots for the most part, and so there
will be weak demand for human mental labor in the future just as the demand for
human muscle dropped precipitously in the past.
6. What If Chicken Little is Wrong?
Despite the strong case for looming
technological unemployment, it is worth considering the possibility that
Chicken Little is wrong. Chicken Little’s dire prediction is based on two
claims: (1) that a large number of jobs presently done by humans will be
performed by computers and robots in the future, and (2), new sectors of the
economy will not generate sufficient jobs for humans (because machines will
supply most of the necessary labor in new sectors of the economy as well). Interestingly,
there is near universal agreement among experts about (1). The residual
disagreement between Chicken Little and the economists is about (2).
It is worth seeing what the economy will
look like if (2) is false and (1) is true. The answer is that there will have
to be massive growth in the economy. Specifically, growth in economic output
will have to be greater than worker redundancy. For example, it might seem reasonable
to expect that if 10% of the workforce is made redundant by robotics, then the
economy would have to grow by 10% to absorb these workers to maintain full
employment. Such a one-to-one relationship is illustrated in the One-to-One
graph below.
However, the one-to-one relationship is not
plausible. Here’s why: Suppose an economy comprises exactly 100 firms with 10
workers per firm who each produce 1 widget per year. ‘Widget’ is to be
understood as the product of the company, it could be goods or services.. This
means that the economy produces 1,000 widgets per year. Imagine robotics and
advanced computers replace only 10% of the work force. It is easy to suppose
that the one-to-one relationship must be correct: the economy must grow by 10%
in order to absorb these workers in order to maintain full employment. However,
this is not the case; the economy would have to grow by more than 10% to absorb
the workers. If each firm now only employs nine workers, the number of
unemployed will be 100 workers. If the economy grows by 10%, this would
translate into 10 new firms. In other words, 110 firms each producing 10
widgets equals 1,100 widgets per year. But 10 new firms would only employ 90
people, because the average number of workers employed has dropped to nine. So,
the economy would have to grow by more than 11% to get back to full employment.
The difference gets more dramatic as the redundancy percentage is increased.
For example, if robots replace three out of 10 jobs at each firm, then the
economy will have to grow by 43% to get back to full employment. For now there
will be 300 people to find jobs for. Since firms now only employ an average of seven
people, 43 new firms will have to be created to maintain full employment. If
robots are able to replace five out of every 10 jobs at present, as suggested
by Frey and Osborne’s detailed study, (Frey & Osborne, 2013), then 500
people will be unemployed in our toy economic model. 100 new firms would have
to spring up, that is, finding work for 50% of the workforce translates into a
100% increase in economic output.

The point, in other words, is that new
industries themselves will likely use advanced robotics and computers and so
economic output will have to increase faster than the percentage of unemployed
to keep the economy at full employment. Graph 2 shows the relationship
necessary for economic growth and full employment.
We are now in a position to see why BIG is
a smart bet, given uncertainty. Either the future economy with massive
implementation of robotic workers will not generate full employment for humans
or it will. If the former, then there is a clear need for BIG. In this case, we
imagine that workers are simply outcompeted by robots in many areas of the
economy. Addressing the needs of displaced workers is morally and prudentially
important. Morally, of course, we ought to care about the plight of our fellow
humans. Even for those motivated solely by prudential concerns, BIG would be an
efficient way to stop social unrest caused by massive unemployment. Those still
employed, in other words, should find BIG an attractive means to avoid the
threat of having their heads put on the ends of pikes by angry mobs upset by
perceived unfairness of the robotic revolution.
On the other hand, if the economy is able
to generate full employment, then the economy will have to grow faster than the
redundancy rate to keep full employment. This means that the economists who
predict full employment must also predict a fast growing economy as a logical
consequence. That is, optimism about full employment logically requires
optimism about a massively expanded economy. In this case, paying for BIG will
be comparatively easy, as it will be a small percentage of total economic
output. As I will show in the following section, a reasonable BIG for U.S.
citizens works out to 12/5% of the economy at present. Using this as our
baseline we can see, that, if 20% of the jobs at present performed by human
workers are performed by robots while full employment is maintained, then
paying for BIG as a percentage of the economy should fall to 10% from 12.5% of
total Gross Domestic Product. If half the jobs are taken over by robotics in an
economy with full employment, then the total cost of BIG is about 6% of this
economic future. So, what makes BIG a rational bet is that either it will be urgently
needed or easy to pay for (and perhaps both).
7. A Simple Way to Pay for BIG: a 14% VAT
The call for a BIG is often met with the
criticism that it is utopian. In one sense, the criticism is about its
political feasibility: is it possible to get enough BIG votes in Congress? In
another sense, the utopian objection is that the U.S. could not afford BIG. I
will attempt to address the latter objection in this section. I have no
expertise concerning the former,
but I hope, perhaps naively, that Congress might be persuaded by good reasons.
This paper is an effort to make the case to voters and representatives for BIG.
Many, perhaps most, authors writing on BIG
do not suggest an amount for BIG. No doubt there is much wisdom in not attaching
a dollar figure, but nevertheless, I am going to stick my neck out and say that
it should be at least $10,000 USD per year in the U.S.
This meagre amount is below or at the official poverty line for most places in
the U.S. In a land of plenty it is far from generous, yet, for many, it would
be enough to stave off the worst forms of monetary deprivation.
Some may say this is not enough, but the
BIG is proposed as a floor rather
than a ceiling. I’m all ears to proposals that call for a higher amount. Notice,
however, that such proposals are entirely consistent with the claim that BIG
should be at least $10,000.
To show that BIG is economically feasible,
let us first work on calculating its cost. As a first cut, there are 194
million adults 18-64 years of age in the U.S. A BIG of $10,000 equals $1,940
billion or $1.9 trillion for this group (Sheahen, 2012, 87). This represents
only a portion of the over 300 million people living in the U.S. The 36 million seniors in the U.S.
already have access to something like BIG: Social Security (Sheahen, 2012, 87). In the future, it might make sense to roll Social Security in with
BIG, but for the present, we will assume that seniors will either collect their
current Social Security or a BIG equivalent, whichever is greater. An
additional 40 billion would be required to top up the lowest Social Security
recipients to bring them up to the proposed $10,000 BIG (Sheahen, 2012). We will add this to our proposed budget, so we need to find an
additional 40 billion to get to the total necessary to finance BIG to $1,980
billion.
So, we are looking to finance approximately
an expenditure of two trillion dollars. A huge number for sure, but in terms of
the size of the total U.S. economy, over 16 trillion (World Bank, 2014), BIG would
represent only 12.5% of the U.S. economic pie.
Allan Sheahen has looked at how the U.S.
federal budget might be amended to pay for a $10,000 BIG (Sheahen, 2012). I am
sympathetic with Sheahen’s approach but I want to explore an alternate means to
finance BIG through a ‘value added tax’ (VAT). Europeans and many others are
familiar with VAT, but for those who are not, VAT is basically a sales tax that
would be added to all final goods and services sold in an economy.
A VAT of 14% would generate sufficient
monies to pay for a $10,000 BIG. The VAT would apply to absolutely all final goods and services. So,
there would be a 14% tax on food, haircuts, books, medical services and so on.
However, consider those trying to live on $10,000 a year when the new VAT is
introduced. Suddenly, their income would not go nearly as far. Imagine they
spend $200 a month on food. After the 14% VAT is introduced, the same groceries
would cost $228 a month. Their share of rent would increase from $300 to $342 a
month. To have the same purchasing power as before the new tax, those living on
$10,000 a year would need another $1,400 to pay for the VAT. So this is what I
propose: increasing BIG to $11,400. As should be clear, this won’t make those
living on BIG as the sole source of income any better off, for although they
have 14% more money, everything will cost 14% more because of the VAT.
Of course this raises a worry: who wants to
pay an additional 14% tax on top of existing taxes? Many might say: “Yes, I
would like to help the poor but a 14% tax on everything is a huge burden.” In
response, I say most of us should welcome VAT to pay for BIG for purely
self-interested reasons. Suppose you have an above average salary of $50,000
per annum. A new tax of 14% would mean $6,100 in additional taxes. Yes, that is
a lot out of $50,000, but remember too that you receive $11,400 in yearly BIG
payments. So, under the proposal, your new total income is $61,400 (your
$50,000 salary plus $11,400 BIG payment). If you spend your entire income, your
contribution to VAT would be $7,540, meaning that you would actually earn
$53,859 or nearly $4,000 more on the proposal. The following graph illustrates
the relationship between income, VAT and BIG.
It may help to walk through some of the
information. The yellow line represents the proposed BIG payment. It is
constant for everyone: BIG is exactly the same for everyone from a homeless
veteran to Bill Gates. The purple line represents VAT, which everyone pays. The
smallest contribution to VAT is $1,400, which a person living on just BIG would
pay. Unlike the current income tax system, the proposed VAT is a “flat tax”
meaning that the same percentage is paid no matter what a person’s income.
Someone making $10,000 a year pays 14%, as does a person making $100,000 a
year, or even $100 million per year. The blue line represents a person’s income
in the present system. The red line represents the change in income (after
paying VAT). In other words, the red line represents present income plus the
BIG payment of $11,400 minus a 14% VAT. As can be seen, the red line crosses
over the blue line at about the $81,000 income range.
The vast majority would do better under
this proposal even though it includes a large new tax: anyone making between $0
and $80,000 a year would be monetarily better off. About 90% of the population
has a net personal income that falls below the cross-over point (U.S.
Department of Commerce, 2014). So, the vast majority of the population would be
better off financially under the 14% VAT and BIG proposal.
Even for the higher income earners, the tax
is hardly draconian. The top income tax rate for high income earners at present
is 39.6%. So, the maximum a higher income earner would pay under this proposal
is 53.6% (39.6% income tax plus 14% VAT). While this may seem like a lot,
remember too, this is a maximum. The difference between the theoretical maximum
and the actual tax paid (the effective tax rate) is enormous. The top 20% in
terms of income pay only 20.1% income tax on average, and the top 1% pay a mere
20.6% (New York Times, 2012). In effect then, the difference between the
maximum and the actual income tax rate is about half. So, the present proposal
for the top 1% would increase the effective tax rate to nearly 35%. Or to put
it another way, if all the loopholes were closed and the richest taxpayers
actually paid 39.6%, then they would be much worse off.
Again, this only applies to the top income
earners. Consider how well someone making $100,000 a year would fare under the
proposal. Looking at Graph 3, we can see they make less, but the difference is
almost imperceptible on the graph. The difference is actually $2,281 in
additional taxes. This would only change the effective tax rate by 2.3% for
those in this income bracket. The relevance of this is that about half of the
10% of the population negatively affected by the tax earn between $81,000 and
$100,000. The additional tax this group would have to pay is very small: at
most, 2.3% of their income.
It may help to note that historically, the
highest rate for top earners was much higher. For most of the twentieth century
the top rate was higher, reaching a peak in the Second World War at 91%. I am
not trying to defend the suggestion at this point, only to put it in some
context.
I have assumed that nothing would change in
terms of other taxes, but we should briefly consider this simple assumption.
With BIG, there would be a greatly reduced need for income tax to support
welfare programs. Conservatively, federal welfare programs are estimated to
cost $400 billion (Sheahen, 2012).These monies could be used to pay the
additional cost of government services with a 14% VAT, reduce the deficit or
offset future increases in income tax.
8. Conclusion
A full consideration of BIG would require detailed
consideration of other policy options, which are addressed by other authors in
this journal. I will briefly, however, say something about welfare and a
shorter work week as competitor policy options.
Many of the hodgepodge of welfare programs
in the U.S. have an ‘actively looking for work” requirement. The U.S., I
suspect, is a world leader in blaming the victim when it comes to unemployment.
When the number of unemployed greatly exceeds the number of jobs available, as
clearly happened during the Great Recession, it makes no sense to say that
everyone ought to get a job. There is a composition fallacy at work. It may be
true that each runner might win the
race but it does not follow that every runner
can win the race. Similarly, even if each
unemployed person could get a job, it does not follow that every unemployed person can get a job. The same reasoning applies
to technological unemployment: if robots have cost advantages over human
workers in many areas, then it is ludicrous to demand that everyone should get
a job. Human workers simply cannot survive on pennies per hour—the cost to run
many industrial robots (Robert Malone, 2006).
We could, of course, consistently demand
that everyone try to get a job,
knowing full well that most will fail because of the price of robotic labor.
But what would be the point of such an exercise? It would probably be a more
useful and less soul-crushing exercise to demand that the unemployed dig holes on
even days and fill them in on odd days. Yes, for most the task would be as big
a waste of time as looking for a job in times of high unemployment, but at
least it would be good exercise. Instead, people who give up looking for work
during periods of high unemployment ought to be treated as selfless national
heroes. If the economy is not producing enough jobs, then those who give up are
making it possible for others to find work. Indeed, anyone who voluntarily
withdraws from the labor market even during times of low unemployment ought to
be celebrated as a hero of the nation too. Such a move puts pressure on the
labor supply, which helps keep the cost of human labor higher than it would
have been otherwise. The higher the cost of human labor, the sooner the robot
revolution will be complete. The sooner the robotic revolution is complete, the
sooner we reach a future so bright that we need shades.
So, if the robotic revolution leads to high
unemployment, it would make sense to eliminate an “actively seeking work” requirement
for welfare benefits. Furthermore, we would not want welfare recipients being
actively discouraged from seeking work. To do this, there should be some means to
allow such work to supplement welfare, rather than being forced to choose
between, say, low paying temporary work and welfare. Such a choice would
discourage people from reentering the work force should any jobs become
available.
Once we see that there ought to be no work
requirement and that work ought to be encouraged by allowing people to
supplement, rather than replace their welfare payments when they have low wage
jobs, then we can see that there are few differences between such a modified
welfare system and BIG.
And to the extent that there are
differences, the advantages are on the side of BIG. One advantage is efficiency.
It currently takes a small army of government officials to run the nearly two
hundred welfare programs in the U.S. BIG would eliminate most of these because
of its uniform nature: everyone receives BIG. There is no need to hire sometimes
officials to make sure that people are looking for work or not double-dipping
by working and collecting welfare or working part-time and collecting too much
welfare. A second advantage is that BIG is less stigmatizing. Since BIG is paid
automatically, those laid off during the robotic revolution need not prostrate
themselves before the welfare bureaucracy.
Shortening the work week through
legislation is another policy possibility worthy of serious study. I’m not
against it in principle. But the goal should to try to match supply and demand
for those who would like to work, not to generate full employment. Suppose we
found that the only way to guarantee full employment is to institute a 10 hour
work week. However, a study shows that half the population would rather not
work in paid employment but would be happier in non-formal work such as writing
poetry, doing wood work, fixing up classic cars, etc. and living on a generous
BIG, while the other half of the population would rather work 20 hours a week
than 10 hours a week. Such a divergence in preferences is not hard to imagine.
For example, some are very happy with freedom from formal work that retirement
grants. Other retirees long to return to formal work, and many do so. So,
shortening the work week may be a policy option worthy of consideration, but it
should be applied in conjunction with
BIG, not instead of BIG. The length
of the work week should be roughly gauged to match supply and demand where
demand is the preference for formal work. It definitely should not be set to
maintain full employment.
