That would get rid of a lot of people that find out the hard way that they've borrowed themselves into a very deep hole. Job prospects, interest rates, cumulative interest, evaluating the small print and so on. There are many ways to get burned on a student loan and there is only one way you can get out, and that way out takes not just skill but also considerable luck and long term stability.
A few of our Canadian employees were saddled with long term versions of these and we managed to get rid of those, and we managed to keep one intern out of debt by paying him enough that he didn't have to apply for a loan.
I don't think student loans are bad in and of themselves, they just don't work out for everybody and for quite a few people that get squeezed by them the risks were not readily apparent when they entered into the agreement.
Student loans are a tool, and like any other tool they required some study and mastery to make the most of them.
