Compare two billionaires.

One stops and carefully donates his money to have the most impact. He ends up "officially broke."

The other doubles down on for profit enterprises, but focuses on those with the most impact, like electrifying a fossil fueled sector of the economy or making us a multi-planetary species. The profits are reinvested to accomplish these goals. He ends up richer than ever.

It isn't clear that the second billionaire is less admirable than the first.
