school's will continue to raise tuition and fees because students have access to an unlimited line of credit from the US government. with the increased tuition monies, schools become businesses, building out infrastructure and overhead, which must be sustained. if they know the loan money is always coming, why not raise prices? it makes perfect sense.
it would be interesting to see how institutions reacted if the 59% of students who receive loans dropped down to, say, 20%, or even better, 0%.
in my opinion, this would force schools to lower prices, down to "market value" (whatever that is, but certainly a lot lower than prices are now), and force market competition, which is ALWAYS a good thing.
