Oh boy I love it when it comes to to this stage of the conversation where I have to explain that those countries were/not true communism/Marxism. Those countries you mentioned dervish are not true Marxist societies but a disgusting morphed form of Marxism and is closest to Stalinism or Maoism than anything else. As you realise those countries were/are a dictatorship which is the first stage of being a contradictory pseudo-communist society. The second everyone is equal... But some people are more equal than others, for there are plenty of/are starving families in those particular countries while the pseudo-communist elite dine with fine foods and wines. May I also mention in a Marxist society there would be no money, all those countries fail amazingly at that one, for money leads to capitalism wether it is Stalins state capitalism or China's Capitalism it makes no difference.

Apologies for that little rant, I just find it my duty to tell people the difference between those countries and a true Marxist society.
