You realize that a billionaire has almost nothing to do with their money but invest it in better equipment or people? That's what investing is and that's what billionaires do with their money. So on the front end the billionaire had to give more than a billion dollars of value to society in order to get people to voluntarily do business with them. Then on the back end they have to turn around and invest most of that money back into society. In doing so they're shouldering the burdens of market research, diligence, and risk. Society wins twice from this and in return the billionaire gets to spend a lot of money. Society wins there, too, because the economy benefits from their ridiculous spending. Does this work perfectly? Absolutely not, but nobody has a better system that I've seen.
