I agree that Healthcare should be a top priority for people, and that minor changes can help pay for it. As a Classic Liberal, I've always been very against socializing medicine in any way. However, over the past few years I've changed my stance. I'm a free-market fan, but I don't see a path for this ever being accomplished in the world of Healthcare. Our current system is so bad and so expensive for both individuals and the government that it simply must change (quickly!).
I think you are right that cancelling student debt won't have a direct impact on the debt, but it will have an impact on a large receivable on the Federal Governments balance sheet ($1.5 Trillion). It still seems crazy to me that Liberals want to cancel student loan debt. It seems so anti-progressive since those with student loans (went to college) on average earn more than those who never went to college. My brother-in-law has $250K in student loan debt and now makes outrageous amounts of money. This guy does not need any of his loans forgiven.
