"I suffered and so should my children! Why should anything get better"
I don’t think that is coincidental. Why would someone support a political party besides thinking that its policies generally were the ones that make things “get better” of the available alternatives?
Weird anti liberal-arts slander aside, the vast majority of people unable to pay off their student loans - most of whom have been trying to do so - are far closer to the former implied end of the socioeconomic spectrum than the latter.
Not that it actually matters - your question is disingenuous to begin with.
Poor fast food workers almost certainly pay zero-to-negative net income tax (negative potential becaue of EITC), so…they wouldn’t pay forgiveness for anyone.
In a world where the Fed both had the capacity and the desire to selectively exclude the effects of particular fiscal actions from its monetary policy calculations and, specifically, to do so for student loan forgiveness, this might actually be a sensible question.
