But even then the vision doesn't directly translate to reality as envisioned. How a "fantasy" gets incorporated into the fabric of society is necessarily affected by the reality of how people are: what they believe, and are willing to believe; how they think, and have the capacity to think; what they want, and how far they are willing to modify what they want; what they fear, and what fears they are willing to abandon. Every vision of a brave, new world is changed by the implementation of the vision (Schrödinger's cat). The Soviet Union was not by any means the workers' paradise envisioned in the Marxist-Leninist fantasy. It could not possibly have been, because the realization of the fantasy was necessarily affected by the fundamental natures of humans.
