My parents are low middle class. We didn’t qualify for any financial aid and they were tasked with trying to find a way to send both my sister and I to college which they couldn’t afford.
So what did we do? Take out a bunch of loans. Good thing I got a decent job that can pay for them. Too bad for my sister who had a masters and is making $35k as a teacher in Tennessee which is barely more than minimum wage.
I believe it's possible to have loans forgiven if you work in certain industries (like public school teaching) for enough years, but it's not a few years — more like a decade or two.
If you think someone who gets a masters shouldn't have to pay back their loans, I'd counter that such a policy would be a wealth transfer from taxpayers to universities. Masters degrees are almost always a negative ROI endeavor, once opportunity cost is factored in. We shouldn't be subsidizing them even further, which will lead people to get even more of them, given how little they add to future earnings.
