Leftists and Memory

I noticed a common assumption on the left side during the health-insurance debates: that if a behavior is mandated or prohibited nearly everybody will, of course, obey the law. They don't believe people will respond to incentives to have or drop health insurance but will respond to a legal requirement to do so.

I have heard that people who smoked enough dope in college don't recall it (or, apparently, that anybody else their age had done so) but I didn't believe that until now…
