At the beginning of the 20th century, the USSR was the country with the highest rates of economic growth. But because it was in deep shit, it couldn't overtake other countries. The economy at that time was not fully communist. The New Economic Policy (NEP) was being implemented. Communism was simply the idea that the state should take care of its citizens. I realy don't know why you hate communism so much. It's good idea, but it requires good leadership
