It would do more good in K12 or pre-K than it would paying off private debts held by white collar highly educated not rich yet due only to their young age university-bros.
I'd say many of these university bros are actually parents to K12 and Pre-K and having parents not terribly in debt could help them focus more on being there for their kids and encouraging education.
It truly is astonishing. We have kids who cannot afford school lunches, people working multiple blue-collar jobs and yet the problems of people who are statistically better off than average constantly jump to the front. People complain about Effective Altruism because of one dude messing up big but it would behoove everyone to read up on the basic philosophy of it before suggesting how we best spent billions to help reduce suffering.
