Okay, I'm catching a vibe that you of of the belief that perhaps communism was never tried true to it's ideological framework? To avoid argument, let's just say that is true. Do you acknowledge the knowledge problem with communism? It's essentially the idea that market prices give us a lot of value. This value allows for the conservation of resources and provides us with the ability to get from point (A) to point (B) as austerely as humanly possible. Without market prices, things get rough, and I think this is why those other systems that started down the road of communism had to quickly shift to despotism until they either failed and admitted defeat or carry forward like China into the nightmare it is today.
