The argument is that wiping out loan debt wholesale will pay off a lot of loans that people are making money to pay off (doctor's, lawyers, Indian Chiefs, etc.). However, a lot of people have a small amount of loans outstanding and wiping out those loans would be an instant boost to the economy. Give a Urologist 50,000 more dollars and he's going to buy some bitcoin or some stock. Give a guy with one year of college who's a delivery driver with 3 kids and 20,000 of student debt the same "assistance" and he will invest it almost immediately in the economy.
I'm not advocating for it. Just pointing out my understanding of the economics of it.
It's really the difference between the left/right. The Trump tax cuts led to many companies buying back their own stock and shareholder growth. Those who benefited from that were the upper echelon and the deficit did NOT decrease as I was told in this forum that it would.
