A friend asked me a question about examples of the way a state functions as an instrument of the current economical system. He said he was in a discussion about the end goal of Communism (moneyless, classless, stateless) with someone that said that without a state, the ‘poorer’ regions would be oppressed by the ‘richer’ regions.

What I’m asking for is examples of the state as an instrument of the current economical system and also examples or theory of how a socialist state with a vanguard party evolves into full communism.

I have read several books about this I think but I’m also blacking out on who and what was written.
