Last week, Matt Yglesias had an extremely insightful critique of the view that unemployment remains high because "we are not as wealthy as we thought we were":
It is both true that we are not as wealthy as we thought we were and
that there's a lot of joblessness in the United States, but I struggle
to grasp a model in which the former causes the latter. Imagine a
reverse situation. A town full of working-class people sees its
unemployment rate suddenly shoot up from 11 percent to 27 percent.
Concurrently, it turns out that the town's residents were much wealthier
than they thought they were--each one of them actually had a check for
$1 million sitting in their pockets. We might say it's pretty clear
what's happened here. These folks are wealthier than they thought they
were so they raised their reserve wage. But then suppose it turns out
the checks were fraudulent and they all bounce. The reserve wage should
fall and joblessness should decline. That it seems to me is the
supply-side story about the relationship between wealth and employment.
Only this morning, though, did I realize that Matt's point is far more general. Consider the following claim:
We can't blame X on poverty because poverty is a reason to avoid X.
This claim makes perfect sense if X=unemployment. If you're poor you need money, and working is a good way to get money. But the claim is equally sensible if X= any of the following:
alcoholism: Alcohol costs money, interferes with your ability to work, and leads to expensive reckless behavior.
drug addiction: Like alcohol, but more expensive, and likely to eventually lead to legal troubles you're too poor to buy your way out of.
single parenthood: Raising a child takes a lot of effort and a lot of money. One poor person rarely has enough resources to comfortably provide this combination of effort and money.
unprotected sex: Unprotected sex quickly leads to single parenthood. See above.
dropping out of high school: High school drop-outs earn much lower wages than graduates. Kids from rich families may be able to afford this sacrifice, but kids from poor families can't.
being single: Getting married lets couples avoid a lot of wasteful duplication of household expenses. These savings may not mean much to the rich, but they make a huge difference for the poor.
non-remunerative crime: Drunk driving and bar fights don't pay. In fact, they have high expected medical and legal expenses. The rich might be able to afford these costs. The poor can't.
Hardly. Few claims are more obvious than "Being poor is a reason to save money, work hard, and control your impulses." The right lesson to draw, rather, is that social scientists need to search for factors that cause both poverty and irresponsible behavior. Such as? Low IQ, low conscientiousness, low patience, and plain irrationality.
