How do they have the money to do this, sustainably?
NYU's endowment is $4.1 billion. They make 7.5%/year on that according to this report: https://www.nyu.edu/content/dam/nyu/investmentOffice/documen...
That's $300 million/year in growth, not counting donations.
Their medical school apparently has 679 students. At $50k/year each, that's $34 million a year. Or approximately 10% of the appreciation in their endowment.
