thats partly because education consumers (students) keep demanding education to cost so much. If everyone applied to and went to the cheapest colleges they could find, universities would be clamoring to reduce their costs, not increase them.

of course, a big part of the problem is employers. Employers place a large value on Ivy league schools and expensive universities, thus creating the consumer demand in the first place.

What happens is that housing prices fall until enough people can afford them.
