Communism is retarded and doesn't work, every communist country (USSR, China, Vietnam, etc.) had to go to a market system to have a functioning society. China was able to do it successfully because they had a competitive advantage in cheap manufacturing and the West didn't have much qualms about offshoring shit there. The USSR was on borrowed time since the 70s, stagnant economy and was never able to keep up with tech progress due to top-down bureaucracy moving too slowly.
