Federal student loans are not just difficult to discharge, they’re practically impossible to discharge. There are so little valid cases for it, you could count them on one hand. And that does not even take into account the fact that the sitting President and their cabinet can just say, “No, **** you.” Even after you qualify and a court agrees with you.
Edit: Just gonna point out that the only guaranteed way to discharge student loans without the federal government possibly overturning the ruling is to simply die. Its an excellent system perfectly designed to ensure that both the public sector and private sector can continue reaping the benefits of social mobility while preying on the most vulnerable segments of the population.
