Student loans not being dischargeable through bankruptcy creates a moral hazard, much like bailing out banks. Banks will lend an infinite amount of money for student loans, because there is no risk to them. Creating free money always devalues it; if you have to work for your money, an education is priced $X because that's the maximum people will pay. If everyone gets unearned money to pay for education, it becomes worth $X + $Y. This is just the SaaS model for people. (Consider AWS; "oh you want to make money selling a SaaS service? we'll take 10% of your revenue for servers." Student loans are the same thing, "oh, you want to go into a high-earning field? we'll take 30% of your income for the next 10 years.")
Compare this to things where banks could lose money, like mortgages. If you bid $1,000,000 on a property that's worth $200,000, the bank will simply require a down payment of $840,000. They have no interest in your starry-eyed games. If you walk away, they can close out your loan by selling the property at the appraised value, and they're happy. Banks have the right amount of paranoia about lending for this kind of purchase; their goal is to never lose money. Student loans should be no different; current grades and expected job prospects should play heavily into the decision as to whether or not to lend money. This will reduce the cost of education because selling a $600,000 art history degree to straight-C students won't be viable in the market anymore. (Universities will fight hard against this, because the degrees are cheap and everyone pretends they have some value. If people realize degrees don't have much value, the cash cow dries up. But we have to kind of look at the effect on society as a whole and realize that work experience is actually what we value. After the first 4 years of your career, nobody cares about your GPA or where you went to school anymore. And incidentally, 4 years is exactly how long college takes!)
> I went to a state school and tuition was $750/semester.
I paid about $800 per quarter in 1996. Even at tax subsidized state schools, tuition has gotten much more expensive since then.
