The people who downvote could elaborate on how this magnificient plan should work. And why it should be implemented? Because communism on paper also seems like a valid idea and then millions die
Plans in general fail as soon as they hit cold reality. There will be problems with implementation, inglorious watered-down compromises, corruption, unforeseen consequences, etc. The funny thing is though that political radicals will not view their original plan as flawed, only the 'deviations' from that plan.
For example, some communists would argue that the reason communism failed was because it deviated from the "paper" version. See 'actually existing communism' and the Nomenklatura (New Class) for more information.
How much more genocides are needed before some crazy idealists realize that communism is a utterly dangerous idea that has little to do with reality? We had/have the Soviets, NK, China, Cambodia and few others with the toll in tens of millions (or more than a hundred) and some entitled middle-upper class pricks still want to "save the world" with this flawed to the core idea?
