Kevin Carey on the trouble with good colleges only being good because they select the best students. As he says, there are a lot of good reasons to want to go to a selective college from the standpoint of rational self-interest "they have nothing whatsoever to do with the quality of education those colleges provide." This, in turn, is a significant policy problem. We should want our higher education system as a whole to be adding value and not just sorting people. After all we could find much cheaper ways of sorting people than providing them with a four-year college education.
