This is kind of how the rhetoric works, though. Talk of student loan debt "cancellation" opens the door for measures of "forgiveness" which opens the door for measures such as you appear interested in seeing.Student loan "cancellation"?
Like all the companies who've loaned out billions of dollars will just cancel them? That would be... unusual.
As someone who took out, and has been paying back, student loans - I think everyone ought to be responsible for paying back the money they borrowed. I certainly don't want to become responsible for paying everyone's loans back through my taxes.
Now, if they want to work to figure out a way to make college affordable (or at least less unaffordable), then I'd be on board with that.
Basically what AOC and Sanders and the "radical" Left is saying, when you read past the scary big-font stuff, is college and post-high school education/training to be affordable similarly to fifty years ago.
Now, like you, I took out a loan and paid it back, so this type of thing sort of "victimizes" me, but I don't care. If we're going to compete in the near- and long-term, then we need to compete. Right now? We're losing, and bad.
