You have confused communism with the Soviet Union.
Over the past 40 years we've had lots of "from each according to his ability, to each according to his need". Look at the social programs in the US. Look at the class envy politics of the Democrats. Look at the slippery slide toward an ever bigger government. The fingerprints of Karl Marx are everywhere.
Although in a sense you're right. What we saw in the Soviet union was actually Stalinism. Still, I think the sentiments expressed in the article are overblown and self-pitying, and PC is alive and well anyway.
