Russia is currently an oligarchy, run by a small elite class. But when it was ‘communism’ it was run by a small group of elites (oligarchy). Before that it was a monarchy run by a small group of elites. Communism and Socialism are just oligarchy rebranded as equality.
Socialism, communism, fascism, and theocracy are all authoritarian regimes run by a small groups of Elites (oligarchs). They just have different branding for the masses. It’s just aristocracy repackaged.
The different ideologies are just different flavors of totalitarianism. The ideology is just academic. To the Elites at the top, and the common man with a boot on his neck, they all work the same.
