Noted your sarcasm, but it would be sad for Harvard and its ilk to get EVEN MORE unaffordable for anyone not upperclass.
They charge this much essentially because they can (govt-subsidized loans), and because it helps them maintain a certain reputation.
Harvard effectively is close-to-free if you are not rich, but why would they subsidize people from rich families?
Govt subsidized loans thing is wrong also, very few Harvard students have any sort of loan.
