The "privileged" are the ones attending college. Cancelling their debt -- in practice -- would be seen as racist/classist once someone runs the actual numbers.

The "privileged" are the ones attending college. Cancelling their debt -- in practice -- would be seen as racist/classist once someone runs the actual numbers. So there would be means testing and possibly race testing, or first generation college student testing. Now you have a dividing line with some people above it receiving nothing, and a lot pro-rated in the middle. Everyone is jealous of those receiving more than they are. The line that schools are getting more expensive because the free-riders don't pay anything isn't going to sit well with those who failed the means test and feel they are subsidizing. There is a strong fracture between the two groups and suddenly we're producing a whole new generation of Republicans. Or nobody takes Warren and Sanders seriously when it comes time to actually elect them outside their echo chamber and this goes nowhere.
