I can't find the source, but I heard most of the newest crop of billionaires made all their money of financialized wealth (ie, not producing anything of value, just arbitraging something - probably mostly real-estate).

They're not exactly doing nothing but they're not producing anything of real value. This is a growing problem in the US.

I agree with your larger points, but also arbitraging away price differences is valuable for a society. It feels like one of the big advantages capitalism has versus planned economies
