Apparently their envy is blinding them. Do they really think that there would be no rich people? Do they think there are no oligarchs in Cuba and other countries? Do they know that Kim3 might be the only fat man in North Korea?
They can go and live as dirt poor paupers in one of those countries.
Having had face-to-face conversations with folks like this, I can honestly say that all that motivates thim is “sticking it to the rich bastards.” That is it. They do not care that they may continue to be poor so long as the “evil rich” are dragged down into the gutter.
