Any of the billionaires that have already died did one thing good by nature of having died.

Trick question.

The billionaires who do good don’t want their names attached to their deeds because that defeats the purpose. The point of altruism is you don’t want credit.

(Seriously there aren’t many, though, because if you’re hoarding money, you’re a horrible person.)

They've all done at least one good thing that's a insanely low bar that's very subjective. Name one that isn't more good than harm in the world? They don't exist.

The problem isn't a billionaire that's done anything good, the problem is a billionaire who has done more good things than bad.

Those don't exist.

There's no amount of good you can do to make up for the amount of exploitation you had to do in order to get to be a billionaire.

It doesn't mean that a billionaire can't do anything good. It just means the world would still be better off without them.

Millburn Pennybags or Uncle Pennybags gave you $200 every time you passed go.
