Since I graduated 15 years ago, the public University I went to has increased costs significantly and massively improved student amenities. Baristas and rock climbing walls and whatnot. Why? It improves rankings and people will still pay for it, subsidized by student debt. If, say, people actually had to be able to afford the bill, I bet all the expensive nonsense and massive staff beuracracy would shrink in no time and the schools would go back to costs being classrooms and books.
