They do have a coming problem though. With the escalation in price and the well known stories of college grads moving back in with their parents, their next set of customers are starting to question if college is for them. Essentially the education industry has started to eat its young and does so even more every time prices rise above reasonable amounts. The other thing to consider is that the cost for college has risen much faster than the label price. Given that most students need loans, when you factor in interest paid and the long term rise in interest rates - the cost of education has REALLY gone up... much more than is reported.
At some point things will correct - either the government will step in (unlikely) or there will be a fall out when inevitably their customers realize that education is more of a liability than an asset.
