Communism is doomed to fail if thrust upon a people that havent been "trained" into its lifestyle, youll always get people saying things like "i work harder than tom, why does tom have everything i do, all he does is push a broom while i have to mine coal... this is not fair i deserve more!" < this mentality is what im talking about.
but to be frank, there has been no pure communistic society, no pure capatalistic society, no socialistic society...
Its always been a mix blend of societys, leaning in one direction more than the other but very slightly....
