Why people with student debt are refusing to repay it

So, evidently, a bunch of people really really really really really really want to believe that in Germany, you aren’t allowed to go to college/uni if you got on the wrong track at a young age, even though that is untrue these days and I’ve said so multiple times on this thread. I find this psychological phenomenon both odd and interesting. What explains it? Moral superiority? Motivated beliefs? Both? Something else? Can someone explain this to me?
