Exactly, people get loans for houses and cars, and the banks make damn sure you're a good credit risk. For college loans, it's
literally the opposite. Since the loans are so hard to get rid of, the only incentive is to increase the number and size of the loans.
The issue is that if lenders looked at creditworthiness for college loans the way they do for mortgages, either the price of college would have to decline precipitously, or they would trust far fewer people with that amount of money.
