I wasn't arguing for communism over capitalism; the main issue I took with your post was the stupid ahistorical assumption that communism and capitalism are two sides of the same coin, that the two could ever interchange or revert between eachother. Communist society comes about by the movement to abolish capitalism, a movement generated by the contradictions present within capitalism. If communism isn't the end of history, then what follows it will emerge out of the contradictions present within communist society and generate something qualitatively different both from communist and capialist society.
The USSR was not communist. It was not close to being communist. It was not progressing towards communism. If you think that the USSR was reeeaaallly close to communism, then you have a completely inaaccurate understanding of both the USSR and communism. Only a few minutes reading the Wikipedia articles on communism and the USSR would show how demonstrably false you understanding is. Considering that you are apparantly too lazy to look these things up before bringing them up, I'll help you by posting links below.
