If what you are saying is true, how come Communism collapsed all over the world? It collapsed because the Communists could not keep up subsidising everything from top to bottom - it came to a natural end.
Only ideal capitalism can save the world - but it does not exist anywhere. USA is not an example of Capitalism. In a proper capitalistic society pressure groups and lobbies have no place - USA is full of them. In a perfect capitalistic society only unfettered market forces dictate terms - not lobbies, Buildebergs, Windsor and other such cartels.
I like to compare Communism with disease - when one does not look after one's body disease sets in. Similarly when there are no perfect market forces in place, the natural outcome is Communism. After all, when one is forced to go hungry, one cannot think in terms of principles - Communistic ideology will appeal to that person. But in the final analysis Communism has no answer and is a failure.
