Socialism is seizing the means of production alone. Communism is a ‘Socialist’ socio economic system were the means of production are owned by the state and all product and labor is divided according to needs. Socialism redistributes nothing on its own. It is simply the means of production owned by the laborers, so a trade union type of system that can exist without authoritarian police state, there are worker owned businesses in the US right now, it’s not illegal to create or operate a business this way, so it exists where people create it and favor it with or without effort from anyone else.
