Seems like most of the countries who try to go with communism are already poor. Russians were starving to death before they became communists and they were starving after the communist party fell. A lot of countries that claim to be communists were not really communists. They were totalitarians. I think European socialism is closer to being a real version of communism than the so called communist countries ever claimed to be. Its against human nature to really be a communist. Humans are greedy, self centered and afraid. That's why it never works. I think the European countries do a better job at coming close to it than anyone else though.
From each his abilities, to each his needs.
