Think about it. Effectively, you end up working long hours doing what the government tells you to work, for what amounts to worthless currency due to only being able to exchange it for what the government tells you to buy. You are housed as and where the government tells you, you are fed how and when the government tells you. If you refuse to work or cannot work, you are put away. You likely do not have a good education, as the government only needs select few to be smart in certain fields, and those certain few are groomed from young age because they show the capacity to learn the important stuff.
In a communist society, the Government is the master, and the common man is the slave.
The industrial revolution fucked over the Feudalist government system around the world. Communism is how they want to get us all back under the rule of emperors and kings again.
