It's crazy the hundred millionaires in the top 0.1% are closer to a homeless person than Elon musk.
I think it's an interesting thought, I'm not sure I have a hot take here or anything. The likes of Jeff Bezos and Elon Musk are clearly good at amassing wealth (and interested in amassing wealth) but I suspect a lot less is attributable to skill than many would think.
So, no, I don't think "he doesn't act like he needs it" is at all a good argument for redistribution.
