Many Communists would argue that they was Stalinism and Sovietism that failed and that Communism was never even implemented properly.

In any case, Capitalism, with religion as its mistress, has resulted in only death, misery and suffering here in the Third World. It's exploitation and ignorance from sub-Saharan Africa to Indonesia. What makes things worse is the interference of Western Capitalist governments into the affairs of poor states. Most of the world is poor and it's getting poorer. Something is obviously terribly wrong.
