Every totalitarian Communist considered themselves as a Socialist first and foremost.

Communism is what happens when Socialists realize that they want complete control over every aspect of human life.

A "centrally planned economy" by definition discourages and despises participation by the masses. It's a bureaucratic oligarchy.

Capitalists desire purchasing power. Socialists lust for the power to plan society. Which is worse?

The desire to engineer humanity is a sign of a mind warped by megalomania and lust for power.

The central planners of Democratic Socialism tighten their noose when people resist their plans and assert their rights. All Socialism is intended to devolve into Communism, and as a result, Totalitarianism.
