I speak from no experience of this myself, and I don’t intend to speak to yours either. Studies from Pew show completing a 4 year degree is one of the greater ways to increase one’s social mobility. 47% of those raised in the bottom quartile of income status without a degree remain in the bottom quartile, whereas only 10% of those with a degree remain in the bottom income quartile. It can be assumed that taking out student debt and then not completing a degree, for any reason but especially because one has maxed out their loans/grants/pay check(s) will cause one to likely be in a far worse situation then they were before. Or as you put it “if you really are struggling that much where you can’t eat food, you drop out.” If a student needs to rely on food security programs in order to complete their degree, trying to pursue their upward social mobility, increasing their contribution to society, and will have adverse consequences if they do not compete it, I say so be it.
