Not a whole lot, though I would point out that it isn't people failing to pay them back...they are the Uber rich middle class as AJ called them. *total aside, but if that's a clever play on words for people driving Uber to make ends meat, well done.
It's a way to keep the economy going and people shopping. A bunch of folks have a few hundred extra to spend each month instead of just paying into a government bucket. While its not likely to happen because of greed, that does create the environment for wage growth for jobs that aren't held by those college debt holders.
