One of the insane demands was the federal government forcing Harvard to hire faculty/admit students expressly on viewpoint grounds to balance depts that lack viewpoint diversity.
Garber could (and probably would) have gone along with the initial set of demands but these go too far.

I went to look up why our “large enough number of ns” guy is so determined to defend this policy and then I learned that his husband has been nominated as Trump’s undersecretary of state for economic growth, energy, and the environment lol

Unfortunately, I don’t think you’re going to like the Bayes rule calculation of the chances you’re fighting critical battles for civilization given people are attacking you.

Ok, this probably won’t pass but it would be a one-time tax of 6% **on the total value of the endowment** not just investment income. That’s ~$3b for Harvard alone, roughly half its operating budget.

I feel like I’m taking crazy pills. In Cambridge at least, it was teachers themselves that were the biggest proponents of delayed school reopening. Parents of the Laptop Class largely wanted schools to reopen asap and many moved their kids to private schools that did so.
