@HistoPol regarding the greed of plutocrats, I think this blog, which I did not know before and am not vouching for overall, nails it.
The main argument is that capitalism was a bridge from feudalism to...feudalism.
I actually disagree on the final point about the end state being a return to feudalism. What we're looking at is a corporatist variety of capitalism.
All fascisms that reached power were corporatist--the plutocrats, oligarchs and corporations run the economy. @CarlG
