Being a founder of a startup, even a relatively successful one, doesn't put you into the same class as the top 0.1% of billionaires.

At the very least you have to exploit the labor of the bottom 99% of society in order to attain 1% wealth.

When you get to the level of Musk, I think it's almost self-evident that it isn't possible to attain that much wealth, without being directly responsible for a significant fraction of all the evil in the world.

That's slightly different from "participating in evil parts of society" but I think that it certainly would be difficult maintain that kind of wealth but somehow avoid participating in the activities of your peers.
