I’m not sure if this should go in history or politics because it could fall under either category really. Anyway why do you think communism failed? Personally I think it collapsed due to the lack of money. The reason I say this is the Communist principle is based on socialism. The Wikipedia definition of communism is this: “Communism is an ideology that seeks to establish a classless, stateless social organization based on common ownership of the means of production. It is usually considered a branch of the broader socialist movement that draws on the various political and intellectual movements that trace their origins back to the work of Karl Marx.” Communism is a style of Governemnt I.e. Democracy, Republic Socialism is as follows: “Socialism refers to a broad array of doctrines or political movements that envisage a socio-economic system in which property and the distribution of wealth are subject to control by the community for the purposes of increasing social and economic equality and cooperation.” Socialism is an economic system i.e. Capitalism The two are virtually the same definition. The problem I believe is simple. Taking lots of money from the top richest 1 or 2% in a true communist dictatorship like in 1939 Soviet Union, will render them poor or middle class. This evaporates the source of large chunks of income for business (because they don't have it anymore, the government does) thus causing buisness to slow or shut down. This in return slows the economy to a halt due to the lack of jobs. The lack of jobs of course created by the lack of money the businesses have to pay the employees. People are jobless, poverty and social decay moves in. Even Communist China is beginning to understand the benefits of capitalist free trade. China is awash in money from free trade with America and the rest of the world.
