For what it's worth, the student loan program is solidly in the black for the federal government.
The profit figure, if annually averaged through 2023, would place the U.S. student loan program among the 20 most profitable public companies in the world, according to Fortune magazine’s annual list of the world’s 500 biggest companies. The bipartisan Senate bill would increase the government’s profit off student borrowers by more than $700 million compared with existing law, the Congressional Budget Office said."

My wife and I have substantial student loans from law school. We got good jobs and can afford to pay. Meanwhile, lots of people don't and can't, and rely on the governments very generous and flexible repayment terms. As long as the program as a whole turns a profit, its a cross-subsidy, and I think that's great. People who take student loans should be uniquely willing to pay to spread out the risk.
If we're going to cap tuition (price controls), why not increase taxes as well? College becomes much cheaper ($10K for your degree, not your semester), and society, the student, and every future employer benefits.
I understand people don't like taxes sometimes. Even me. But with them, I buy civilization.
