Right now the way it works is that you get an 8-month buffer between school ending and repayment, and if you can't pay your minimum you apply for the Repayment Assistance Plan where they pay the percentage of interest you can't afford, and you make a payment based off of your affordable payment. The program itself is pretty much guaranteed as long as you can prove you can't pay.
With this, they would extend the 8-month buffer to indefinite as long as you make under 25,000 a year, which would help substantially because it would ensure Students under federal assistance become on stable ground before forcing the repayment on them, which is much better than going off of the "oh, you'll find a job within 8 months no problem" metric
