Like I said here https://news.ycombinator.com/item?id=33438628, we can eliminate 40% of those 310M on the basis that they don't pay federal taxes. So they aren't paying for student debt relief. Of the rest, a good proportion are related to the 22M who are getting the relief. We're talking about parents who are financially supporting their adult children. Or kids whose parents are paying off student debt. It's way more than just 22M.

And it's certainly way more than the number that benefited from propping up the stock market in 2020.
