Don't underestimate what one person can spend. If your reference point is a billionaire lifestyle with a giant yacht, half a dozen estates on multiple continents with staff to manage them, and a private jet capable of crossing oceans to ferry you between them, then with $65B all that is a drop in the bucket and you've got plenty left to spend on whatever political or philanthropic causes you wish, and with $100M you actually have to economize.
