It's not for me to tell the wealthy & powerful how to redistribute their fruits. But... I would think it's more effective not to give so much to a single entity. Instead, provided grants that aren't tied to a particular school. Let students apply (or be nominated) and then decide. Yes, that adds some overhead. But the effect will now be ubiquitous and not limited to a single bottleneck.
I welcome the donation, but I am suspicious of what ensues. Given the mix of public and private tertiary education and the mix of debt and grant funding, It's pretty complicated. If this levels-up Johns Hopkins against the ivy league, remember its still private education. It won't neccessarily redress all the imbalances inherent in university study. It might help, it might hinder. Its not clear
(on an individual level, I am sure it will help enormously. I'm trying to draw a distinction between individual benefit, and societal benefit as a whole)
