There's extreme moral hazard, on that note, in an education system which requires those seeking better opportunities to pay out of pocket - and thus necessitates such predatory loans in the first place.
For the worthless schools that took loan money and didn't deliver education (for-profit scam schools), those could be forgiven. For all the expensive degrees that have led to jobs that can't pay the loans back, this all shows how inadequately prepared the students were to do basic arithmetic and cost/benefit analysis. That's on their parents.
