Right, and the debt mountain occurred in part because the government was irresponsible when they made student debt extremely hard to discharge, compared to other sort of government debts.
Since the government was also responsible for the mountain, they also need to be part of the solution. Which can include forgiving debt.
Had normal bankruptcy law applied, the accumulated debt would be nowhere near this high.
It isn't, however, a justification for why student debt should be treated so specially.
