Interest rates should be capped, and only fixed. So much of the problem is that - even people trying to pay back - see very limited progress due to unnecessarily high interest rates. I don't think any student loans should be granted for for-profit or unaccredited colleges–though really all colleges are for profit.
Parents, communities, high schools, and colleges need to stop messaging "college or else." I think that's changing, but likely was at its peak in the late '90s and early '00s.
Online colleges / learning and "bootcamps" are truly democratizing continued education. I'm certain we'll see more kids choosing this route over traditional four year universities.
Something I wish more students would take advantage of is ROTC. Everyone I know who went that route is thankful for the experiences, "job" after graduation, and lasting career opportunities after their service period. I think a ton of students will find they can both go to their dream school and not have to worry about the loans.
All this to say, I think the millenials / gen-X with high student loan burden, will continue to struggle. Even if the government intervenes, it would probably only apply to government loans, and it's really the private loans that have the super high interest rates, unfair forbearance terms. I'm hopeful for Gen-z and beyond though.
