I don't think you can become a billionaire in an ethical way, without exploiting hundreds or thousands of people below you.

To me, the "good" billionaires participate in and create the system that keeps everyone else poor and without resources just as much; it's just that they throw a few coins back to charity - what looks like a lot to us, but isn't much to them - to a) make themselves look good and charitable or b) assuage any guilt they feel for their continually exploitation of workers and hoarding of wealth. Like a king gathering so many taxes all the peasants are destitute, then tossing some gold coins into a crowd and getting called generous for it even though it's a pittance compared to what they took. There is no more powerful PR for a billionaire, no better way to steer public and media opinion, than strategically giving their money to charity.

They maybe aren't intentionally evil, but if a bit of charity makes people praise them, and makes them feel like they're using their wealth for the greater good, such that they can feel like they're good people and sleep at night, I think they conveniently fail to think through whether the "good" they do by handing out their wealth outweighs the harm they caused by taking such an outsized share - one much larger than they ever give back - in the first place, because anyone would be extremely motivated to come to the conclusion that it's ethical to keep being an mega-powerful billionaire.

If they didn't exploit workers and hoard so much wealth in the first place, their "charity" wouldn't be needed because all that wealth would be much better distributed to begin with, and it would be distributed more equitably rather than on the basis of whoever most appeals to an individual billionaire's whims at a given moment. As it is, they're like middlemen between workers and the causes that need funds, and in being so they are able to wield ridiculously outsized political power (via donations, being treated as important enough to talk to politicians, market manipulation, etc), and they will always oppose any measure that truly threatens their continued power and wealth.

Also they rely on our current capitalist system that requires the line to go up forever, with companies expected to make more and more money year after year (often by taking more and more from their workers), with no answer to where or when the line can stop going up, which is an incredibly stupid strategy on a planet with finite resources and a global warming problem.
