Hmm. I did notice the funny, overly-symmetrising perspective, but I couldn’t place who it sounded like. I guess that’s because I don’t know any billionaires.

In addition to the contemporary takes, “fascism is right-wing dictatorship and communism is left-wing dictatorship” isn’t an entirely useless way of putting it, but it’s close. Left and right are very situational, and there’s been left wing dictatorships that weren’t very much like the USSR, and plenty of right-wing monarchies that had none of the populist vibes fascism runs on.
