How much does increasing college-going rates matter to our economy and society?
Caplan: College attendance, in my view, is usually a drain on our economy and society. Encouraging talented people to spend many years in wasteful status contests deprives the economy of millions of man-years of output. If this were really an "investment," of course, it might be worth it. But I see little connection between the skills that students acquire in college and the skills they'll need later in life.
