Or you can spend it on corrupting society, which can help make you more money. Which brings us to the favorite use of money of billionaires, using the money to make more money!
Because whomever has more wins.

You can buy politicians, can buy (more of a complicated tiered leasing situation with politicians and their appointees and agency leaders,) agency heads, appoint a former lobbyist for your companies' trade groups to lead the enforcement of regulations on your company. Buy studies saying something unsafe is safe, starting with cynical science outfits paid to start at safe and design the study to get there. Then pay to get it published and supported, then pay to lobby, pay to get politicians and their appointees to pretend to believe it. Pay the courts and their proxies, (I'm sure this is a lot worse than we think, not just Clarence Thomas style either,) and then rules are changed, or not enforced, and you make more money than you spent corrupting everything.
