Economic Facts and Fallacies
JANUARY 22, 2009 by GARY M. GALLES
You don’t have to read far to find the focus of Thomas Sowell’s latest book, Economic Facts and Fallacies. It begins by quoting John Adams—“Facts are stubborn things; and whatever may be our wishes, our inclinations, or the dictates of our passions, they cannot alter the state of facts and evidence”—then immediately argues for the importance of debunking economic errors because so many policies are based on false beliefs and fallacious thinking.
Economic Facts and Fallacies exposes an array of widely held beliefs to careful logical scrutiny and evidence—evidence that is usually ignored by those who favor interventionist government policies. Time and again, readers are shown that support for expanding government control arises from mistaken reasoning and interpretation of data.
First is Sowell’s discussion of four core fallacies we frequently encounter in public-policy discussions: the zero-sum fallacy (ignoring that voluntary economic arrangements are positive-sum); the fallacy of composition (particularly that robbing Peter to pay Paul benefits society simply because it benefits Paul); the chess-piece fallacy (assuming that some authority can achieve desired results as though he were moving chessmen on a board, ignoring people’s desires and incentives); and the open-ended fallacy (that commitments to ever-more health care, safety, open space, and so on, are sensible in a world of scarcity).
Even if people read only that section, they would greatly benefit from Sowell’s logic.
The bulk of the book consists of six chapters dealing with subjects where economic misunderstanding abounds: the urban economy, male-female comparisons, academia, income, race, and the Third World. In each of those sections Sowell rebuts a group of beliefs that are widely accepted despite their fallaciousness and incompatibility with the evidence.
While the whole of the book is enlightening, Sowell’s discussions of affordable housing and income comparisons are particularly powerful. I’ll concentrate on them.
Most Americans believe that government intervention is necessary to ensure that there will be enough “affordable” housing. Sowell challenges that notion with a barrage of contrary evidence, including that 1) people paid smaller percentages of their income for housing before the era of government intervention; 2) housing prices rose sharply when more pervasive government regulation began; 3) housing prices in areas with more government intervention rose more rapidly than in areas with less; and 4) growing population and income did not result in far higher housing prices where builders were allowed to construct more housing.
In short, government intervention in the housing market is the problem, not the solution. Sowell writes, “It is precisely government intervention in housing markets which has made previously affordable housing unaffordable.” The next time you hear someone claiming that there is a shortage of affordable housing due to a failure of the free market, you can haul out the book and show that the failure does not lie with the free market.
Sowell similarly devastates income comparisons that twist the data to get whatever conclusion is desired to justify political redistribution. He points out many ways that those who want to create the impression that the United States faces an income distribution “crisis” rely on misleading statistics. For example, there are substantial differences between real income growth per household and per capita (from 1969 to 1996, the former rose only 6 percent in America, while the latter rose 51 percent). By emphasizing only the first statistic, it is possible to create the impression that income growth has been fairly stagnant.
Another way of misleading people is to focus only on income data and ignore consumption—consumption by people in the poorest quintile is actually twice their income, but that fact is usually ignored. Moreover, the idea that there is an income crisis is greatly undermined if, instead of looking at “snapshot” data, you consider the high degree of income mobility. The latter data tend to be ignored. With this section, Sowell shows that it’s unwise to jump to conclusions based on highly selective facts.
Economic Facts and Fallacies highlights many instances where questionable if not downright foolish policy choices were made. So why don’t we change them? Sowell writes, “Many beliefs which collapse under scrutiny may nevertheless persist indefinitely when they are not scrutinized, and especially when skilled advocates are able to perpetuate those beliefs by forestalling scrutiny through appeals to emotions or interests.” This book makes it harder for such advocates to keep pulling the wool over our eyes.
