We need to be able to discharge student loans in bankruptcy - no exceptions, no fine print, no ifs, ands, or buts. Income-based repayment plans are touted as a panacea, but hardly anyone qualifies for them (your loans are too old, you consolidated your loans, name an excuse, any excuse). Loan forgiveness options are so limited that, again, hardly anyone qualifies for them.
Elizabeth Warren's proposal will only help people who are just starting college now. Those of us who need help the most - the ones who have been unemployed for 10 years and can only watch helplessly as interest accrues - don't qualify for the lower rate.
Is bankruptcy a radical option? Sure. But it's one a lot of us need.
