That was very interesting, Dr. Schafer.
On your last point about the economy and crime, would it not be accurate to say that crime has more long-term causes many of which could be economic? For example, the persistence of youth unemployment over many business cycles results, sometimes, in a kind of criminal gang-related underclass or a drug subculture.
One has trouble intuitively understanding that if someone is laid off at the local GM plant, that suddenly they go and rob a bank or whatever. Would you say that the link is more long term and, as you say, maybe endemic, that if we don't deal with youth unemployment quickly, we end up creating this stubborn problem that may only go away with an aging population?
