But is it really worse than the current situation - where people borrow to study something enlightening but economically questionable, and then struggle for decades as they can't pay the debts nor declare bankruptcy?
I agree that studying arts is worthwhile, both for the individual and society as a whole. But there has to be someone to tell the 18-year-olds that they can't borrow $100k for it, or they are making things worse for themselves.
Perhaps if banks adjusted loan amounts to potential future income, then arts faculties will be forced to lower tuition fees. And some students will correctly see that they just can't afford it - better to discover that before starting instead of after graduation.
The hypothesis is that if students can't get the loans then the schools can't charge as much and have to become leaner. Combine this with a social change in perception of "you need to go to college to be successful" and I think the idea has merits. Simplified and not the full answer, but it definitely has merits.
I stand by my point because banks shouldn't be in this position. People aren't companies and they shouldn't be looked at in terms of returns. I (and this is my completely personal opinion) think either education should be free or only the government should provide education assistance.
