One thing consistent with these democrat, Swamp Rat "billionaires" is nobody really knows how they obtained all their cash.
According to Wikipedia Tom Steyer graduated from Yale and was hired by Morgan Stanley in 1979, maybe a $100K salary tops . Then he attended Stanford graduate school and was hired by Goldman Sachs in 1983, maybe a $150K salary tops. Then after two years he became partner at Hellman & Friedman with democrat Robert Rubin, a private equity company and apparently simultaneously founded Farallon Capital with $15,000,000 someone gave him. At this time In 1987 he made a sales pitch to Yale to handle all their cash. Yale said, no problem. And then other Academic institutions allegedly opened accounts with him. Very strange. A kid with literally no investment experience able to convince colleges to give them their endowments to invest? Follow the money!
