I had a college professor back in the early 70s who felt that communism was appropriate for some societies and not for others, and would, in the cases of very poor countries, eventually lead them to capitalism. A communistic period allows a poor nation a chance to eliminate the rampant corruption that comes with many capitalist systems and to implement egalatarianism, and then allows it to return to a more stable capitalism. China is a prime example of this idea in action. Prior to the Communists, the government of Chiang Kai Shek was one of the most corrupt, murderous dictatorships on earth. Communism was a vast improvement for the Chinese people. The same is also true in Russia, Vietnam, Laos, Cuba and Nicaragua. All of these societies have benefited from communism, and have or are now becoming sustainable capitalist societies due to the fact that ruling fascist juntas or corrupt ruling classes have been eliminated. Eventually communism, once it has outlived its usefulness, collapses of its own inherent contradictions. The same is also true of purely capitalist systems, which invariably become utterly corrupt human greed machines. They collapse in the same manner, as it did in the US in the 1930s. In the end, both systems lead to Social Democracy, which is the governmental system that has become prevelant thru out the globe in one form or another and is proving to be the most sustainable long term form of government. The US is totally against the current of history, as the Republicans attempt to turn the clock back to 1928. History has shown they will destablize our society and start the process back towards the equaliabrium of Social Democracy anew.
