Great question! Mostly it goes toward maintaining the campus and paying the admin folks. PIs are paid to teach, basically, and are expected to pull in the money to support their own research (and maintain their facilities and pay the admin folks).

It goes towards MIT’s endowment, which is valued at over $27B, and grew $3B last year.

There is no shortage of money.

		> There is no shortage of money This is a general theme in the last decade. There is a lot of money, but it is more and more ending up in the pockets of the extremely wealthy. I'm really no communist, but we've reached a point where the system starts to crumble because of it. It also can't be in the interest of the billionaires. They also want to live in a safe country and use working public infrastructure (roads, airports, air traffic control). They even need a functioning academic ecosystem if they want their children to receive a real education, not just access to a few famous professors they can buy.
