You have to provide evidence to support your assertion. Communism failed because Communism is fundamentally about using force. In a Communistic country one can never know if a trade is productive because there are no free trades. Thus, some trades are productive and others are unproductive and inadvertently result in the loss of Capital. Over time robbing society of its prosperity. Thus, it's not that Communism failed because its pure, but because Socialism doesn't work to facilitate free productive trades. Thus, as Communism gave wa to SOME free trade, less unproductive trading occurred and society began to create capital and become prosperous. So, while you could say, oh, it was less pure Communism. This is true, but the reason wasn't less Communism is was more Capitalism. China is now ranked 5th in the world in terms of Capitalism and it is reflected in their massive numbers of productive trades and surplus of Capital. Incidentally, Germany is ranks top. As for Standard Oil, oil was cheaper BEFORE Standard Oil was dismantled. The Rockefeller fortune quadrupled after it was split up. The same thing happened with the aluminum, one company had a monopoly and was broken up and the price went up. IOWs the evidence suggests that (a) monopolies are very hard to form and (b) once formed, which really only happened in the one case, in a free market is hard to maintain and requires a lot drive to keep the price so low, lower then otherwise normal, to prevent competition from entering that market space. A lot of evidence is counter intuitive but that's only because we've live through a lifetime of State propaganda telling us that violence is peace and peace is violence. It's why you have someone arguing the worker should pay tax when he sells his labor. Which is the exact opposite of what would happen for any other service. Or that the Farmer, the one who grew the apple, should pay TO SELL his apples. It's completely asinine and backwards. And, that is NOT how this Nation was founded and built.
