The economist offering this “solution” has been feted by
the Obama White House economic staff, the International Monetary Fund, and by
many of the people running world economies today. His ideas are definitely “in
play.”
Thomas Piketty, the forty-two year old French economist
whose book, Capital in the Twenty-first Century, became an overnight sensation
and unexpected bestseller, is being hailed as the new Keynes, an economic
thinker who can lead us out of our current economic malaise, just as Keynes is
alleged by his followers to have lead us out of the Great Depression.
Keynes’s keynote book, The General Theory, is loaded with
economic theory. There are only two pages of data in that book, and Keynes
dismisses the scant data he cites as “improbable.” By contrast, Piketty’s new
book, Capital in the Twenty-first Century, is stuffed with data. Indeed Piketty
considers himself a successor to the economist whose data Keynes dismissed,
Simon Kuznets. Almost everyone admits that Piketty’s theoretical case is weak —
but, his supporters say, look at all this data. You can’t argue with this mass
of historical evidence!
Let’s take a closer look. Piketty’s primary argument is
that wealth (which tends to be concentrated in few hands) grows faster than the
economy, so that those with a lot of wealth keep getting richer relative to
everyone else. This is supposed to be an inescapable feature of capitalism. (If
this sounds familiar, it should be. It echoes both Marx and Keynes, although we
should remember that Keynes mocked most of what Marx said as “hocus-pocus.”)
So what then is the evidence that wealth has grown faster
than the economy?
We’ll start with the chart below, adapted from Piketty’s
book. The top line is return on capital and the bottom line is the economic
growth rate. The top line is supposed to be how the rich are faring and the
bottom line how the average person is faring. Note that the lines on the far
right are just a projection of Piketty’s, and not actual history.
This chart is astonishing for many reasons. First of all,
it suggests that capital earned a 4.5 percent or higher return for the years
0-1800 C.E. This is a crazy number. If the human race had started out with only
$10 in year 1 and compounded it at 4.5 percent a year for any series of 1,800
years, by now we would have much, much more than a trillion times the entire world’s
wealth today, which is estimated at $241 trillion by Credit Suisse.
The 4.5 percent or higher number is also crazy because
Piketty is right that there was negligible economic growth prior to the
industrial revolution, and such high returns for the rich are just not
consistent with so little growth. The truth is that rich people for most of
those years were interested in spending or hiding their wealth, not in
investing it, because wealth out in the open was likely to be stolen, if not by
bandits, then by government.
If you look closely at the more modern part of the chart
and ignore the projection into an unknown future, you will see that the lines
do not support Piketty’s thesis. His idea that the rich will always necessarily
get richer relative to everyone else under capitalism is not supported by the
data he presents.
The next chart shows the share of wealth of the 10
percent richest in Europe over time (dark-blue, top line), the share of wealth
of the 10 percent richest Americans (the light-green, second line from top),
the share of wealth of the top 1 percent Europeans (the light-blue, third line
from top), and the share of wealth of the top 1 percent Americans (the
dark-green, fourth line from top). This chart doesn’t support Piketty’s thesis
either. Yes the share of the rich has grown since 1970, but only after falling
previously.
The next chart is one that I have commented on in an
earlier article. It shows the income of the top 10 percent in the US over time
as a percent of all income. Income in this case includes capital gains which
arguably are not true income, but rather the exchange of one asset for another,
and excludes government transfer payments which make a considerable difference
to the results. Even so, once again we do not see an inexorable rise in the
income of higher earners over time, far from it.
What we actually see is two peaks for high earners, right
before the crash of 1929 and again before the crash of 2008. These are the two
great bubble eras in which government printed too much new money, which led to
a false and unsustainable prosperity. These were also crony capitalist eras, as
rich people with government connections used the new money to become even
richer or benefited from other government favors.
Unfortunately world central banks have blown up yet
another bubble in capital markets following the crash of 2008, which has again
brought the high earners share back to 50 percent in 2012, based on data that
became available after the book’s publication. This newest bubble too will
eventually burst and bring the share back toward the 40 percent level of 1910,
the start of the chart.
Perhaps the most astonishing claim in Piketty’s book is
that government bureaucracies need to be reformed so that they can make most
efficient use of all the new income and wealth taxes that are recommended. The
assumption is that almost complete government control of the economy would be
best, but that the machinery needs some fine tuning.
Economist Ludwig von Mises demonstrated almost 100 years
ago that a state managed economy will simply not work, because among other
problems it cannot set workable prices. Only a consumer run economy can do
that. Socialists have been trying to disprove Mises’s thesis ever since, but
have never succeeded. Piketty should at least read Mises.
A state managed economy is also unable to save and
invest, especially invest with intelligence. This is crucial, because it is
quality, not quantity of investment that matters most for job creation.
Piketty says that taxing away the savings of private
individuals is a better choice than alternative ways of controlling inequality
such as communism, protectionism, or capital controls. But none of these
approaches will control inequality; they will just create poverty for everyone,
rich and poor alike, without ending inequality.
A significant wealth tax would be self-defeating from the
start. It would destroy the stock, bond, and real estate markets. With many
sellers and few buyers, wealth would simply evaporate.
