I feel like you’re misrepresenting or misunderstanding what communism is. You might base your opinion on the soviet union but they never actually achieved communism, and some would even say it was state capitalism and not even socialism. In fact it’s unlikely we’ll ever see what an actual communist society would be because it’s very much a vague utopia, and just a goal to strive towards.

Communism by definition actually isn’t very clear because Marx never actually got into the details of how a communist society day to day life would look like. But he did postulate the primary idea of communism: “From each according to his ability, to each according to his needs.” One idea of communism is that it’s stateless and classless, meaning there literally couldn’t be a small portion of people getting a large portion of wealth. Marx himself actually said that future communist institutions should be designed to be decided democratically by the people.
