The soviets also thought the same, unfortunatelly a system with bad actors cannot be solved from within. Especially when the "bad" actors controls means of production and distribution, and have incentives to continue acting such and in return creating incentives for "good" actors to imitate the "bad" behaviours. Anyway, defining what's good and what's bad when you are an actor within a system is a very subjective exercice, a seemingly "good" actor will turn "bad" overnight given the right incentive and vice versa. The real question is determining who distributes the incentives, and who should. And for all the systems in this world, it spans from random to being concentrated in the hands of a few oligarchs or a single dictator.
