To me both communism and right-wing (brutalist aynrandian) capitalism are the same in some sense. Both are somewhat nice ideologues in naive theory. But if you bring them to real world, communism brings you Soviet Union and right-wing capitalism brings you regulatory capture moochers or warlords, depending a bit on your flavor of capitalism.

The major difference is that only some insignificant weirdos in the fringes have not agreed that communism is stupid in practice. Brutalist aynrandian ideology is much more prevalent problem and needs to be somehow gotten into same ridiculed state as communism as an actual feasible ideology.
