University endowments at alite universities keep getting bigger and bigger. They earn, weigh more on their endowment every year than they need to balance the books. Princeton is a perpetual motion cash machine. There is literally no way they can ever run out of money. If they wanted to build a half a billion dollar dormitory with marble staircases, mahogany floors and solid gold bathroom fixtures, they could pay for it out of petty cash and still bank 200 million dollars. That' wiggleroom.
