> it means that lenders have no incentive to do any due diligence.
That's hard to do because young students haven't had time to build credit history, you can't extrapolate creditworthiness from SAT/ACT scores without hurting students from poorly-funded education systems, and most importantly by rejecting to offer loans, you are preventing a student from a shot at their dream school which could pull a whole family out of poverty in a decade.
The problem isn't how the loans should be disbursed, managed, repaid, or forgiven. The problem is that the base tuition is so high that students need loans. Loans should be for housing, gym memberships, extra-curriculars. I am absolutely ok with my Federal, state, and local taxes funding actual education, not college stadiums. This would also incentivize schools to reduce costs for the basic education and charge people who can afford to pay for the full "college experience."
But over the years state governments keep cutting funding for colleges and universities and students keep having to take out loans. And since loans are easy to get and cannot be discharged, everyone is incentivized to do anything to get more students who will pay a higher tuition. It is a terrible cycle that I hope either gets obsoleted by virtual education, trade schools, or some miracle.
