Student loans can't be made at reasonable interest rates without either a strong guarantee of repayment or a taxpayer subsidy for the risk. The current system has a bit of both.
They hedge the risk by charging a lot more. Do you want student loans at 30-40% APR?
I want student loans eliminated and universities to be government funded through taxpayer dollars, as was the case previously with public universities. Public university tuition has gone up because government funding for them have gone down. As usual, stealing from the future.
EDIT: I'm okay with raising taxes to pay for education instead of the broken student loan system, forcing universities to limit what they charge, and democratic socialism as a whole. Societal utilities (healthcare, education) are not a free market. Never have been, never will be.
I'm not a fan of socialism. I think people and organizations should be free to decide how much their services cost.
And btw, that 15% cap will result in one thing: poor people not being able to get credit.
And yet, credit cards (unsecured lines of credit with no recourse in bankruptcy) are issued continuously to this cohort.
