Yet those “good” kind of uber wealthy would also be lined up before the firing squads. They are what Lenin called useful idiots.
Not necessarily; remember the character played in Dr. Zhivago by Rod Steiger? He is in with the power establishment under the last Tsar, goes to the fanciest of society parties and is protected legally from whatever he does to exploit people without money or influence. When the communists take power, Steiger is suddenly the local Red commissar, still stealing, acting immorally with impunity, and getting away with it. People like this adapt; whatever they profess publicly, their interests are in themselves and protecting their own advancement, to Hell with the rest of you or their country.
