Communism

I don't think that has materialist backing, and therefore lacks scientific explanation. Why do you say the few will coerce the masses? What decides who the few are? Are all organizational structures of society necessarily the same when it comes to this "rule?"

I would argue that Class is the foundation of the primary contradictions within society. It is through social relations that we are organized, and it is through control and ownership of the Means of Production that this power has weight. I see no reason why a publicly owned and planned economy would have the same issues with power dynamics as one where the Means of Production are owned by the few, with the many forced to capitulate.

You do understand you're in a communism community right? In order to address those few exerting unjust power, you must learn about how capitalism enables exactly this problem.
