Earlier quoted context omitted.
Like toomuchtodo mentions, we could treat it like other unsecured debt (like credit card debt). Just because it's unsecured doesn't mean we shouldn't be able to discharge it with bankruptcy. Get the government out of the loan business and the market will correct itself. You won't be able to get a loan for a useless degree and if you end up being unable to pay off your loan you can go through normal bankruptcy proceed…
Would tuition also follow by being more affordable? The government guarantees loans for everybody so institutions jack up their fees accordingly it seems.
http://www.economist.com/node/21559618 quoting a research paper:
"With all factors present, net tuition increases from $6,100 to $12,559. As column 4 demonstrates, the demand shocks — which consist mostly of changes in financial aid — account for the lion’s share of the higher tuition."
And then:
"so much of the subsidy is translated into higher tuition that enrollment doesn’t increase! What does happen is that students take on more debt, which many of them can’t pay."
