Assuming just $10m for 2 of his children to be admitted? That’s enough to fully fund the education of ~50 low-income students [1].
I personally believe we should turn these quiet donations into a public bidding process instead to maximize what colleges can receive and ensure it’s done in as fair of a way as possible, but that’s separate.
[1] It’s important to distinguish that the donations went to the university, not a corrupt official at the university. This is actually productive.
