It unravels because it's one of many systematic cuts taking wealth out of the hands of the middle and lower classes. Income after graduation is routed back into the student loans instead of going into savings (and getting max compounding early on), or going into the economy (giving steam to GDP..). Will it the straw that breaks the back of our current economic expansion? Or will it combine with current tax cuts to pull so much money out of "main stream" economic circulation that we hit another recession? I'm not sure anyone really knows.
