I mean I sold 4 years of my life to the military to not have to take loans out, so I get the gut reaction
The main cause of the student loan issue is the commodification of education. Everyone wanted to go to college and at first it was optional but then as more people did it it became a requirement, then they realized they can charge more and more for education that is worse and worse because a good chunk of people dont actually want to learn / be there. They're just there for the paper that'll let them get jobs and not be unemployed, or even just to say that they went.
I look around and people are playing damn Pokémon Showdown in class, there was that one scandal of an influencer girl who was the daughter of someone important that bought her admission to Stanford(?) and would stream literally about how she didn't care about education she just wanted the college experience.
Hot take: Not everyone should be going to college, High School should just prepare people better. Even if we forgive all loans right now it doesn't fix the issue. Instead of your problem it will just be your kids' problem
