Bezos and Musk, finding themselves in a capitalist society, are playing the game to win. In part, though, they play because that's how they can build what they want to build. I think it's a misunderstanding of the mindset of these people to think they somehow desire the suffering and poverty of others; that's incidental. Not that that's really ok, but if the technology existed to implement The Culture I think they would honestly prefer that to their current positions.
