There's no shortage of great community colleges, though; the problem is that elite institutions in particular are being made artificially scarce for certain groups of people (Asian-Americans in this case) by government fiat, as well as the fact that prestigious institutions are valued because of their scarcity and exclusivity. If they managed to increase their admissions by a factor of ten, then the value of their degrees in the eyes of society would decrease because amongst other things this would mean that they would have to be less selective about who they accepted.
