Maybe? There was a time in the recent past where any college degree could get you a good job in nearly any field. That is no longer the case. Also, one would expect that students move with the economy, but that doesn't appear to happen, either.
My gut says the problem can't be solved by changing the nature of students. If they go to school without regard for job prospects, and we continue to believe that education is important regardless of job prospects, then we should look for other solutions. Changing human nature doesn't seem to me the best way to go about that when there are many other issues at play accounting for boomerang twenty-somethings (high school debt, mostly government issued, appears to be the lowest hanging fruit).
