It can just disappear. Tax payers already picked up the tab. There is no additional expenditures needed.
So the universities and debt holders just eat it? What about all those who already repaid their debt?
The government would. The government loaned that money in the past or else it wouldn't be "debt" and the money has already been raised and spent. Cancelling the debt is the easy part. It is providing free college going forward that would be more problematic.
How is it easy? The Govt just eats it? That’s insane.
The government already ate it when they loaned the people the money. I am not sure why this is such a difficult concept for you to grasp. The government only had to come up with the money when they sent the checks out to begin with. They don't have to come up with a single dime to write-off the debt any more than a credit card company would if you stopped paying them because the money was already spent in the past.
So when the debt is repaid who gets it? The tooth fairy? If I borrowed money from a Bank, who pays the Bank back?
The government cannot cancel your bank loan. It can only cancel the debt you owe them.
