No dictatorship has been communist. They use the mantle, that it's for nation and country, but they don't even pay lip service to communism ideals and mechanism. They are just crony capitalist, where the head of the state is the one that uses the state to control the economy rather than the rich doing it by proxy.
No, I'm blaming the ills of humanity on humanity. Capitalism isn't a system that existed till... like 180 years ago. The industrial revolution didn't happen when "capitalism" as a concept existed. Capitalism existed in the time that Marx was alive. Also, I'm muddling concepts? No, the public doesn't know crap about this stuff. I studied 6 years economics, so I have become very annoyed when people call communism or socialism to countries that were neither just because their governants called themselves such.
Read any good book about history of economic theory and thought, you will see that the crap that people talk about on tv and the internet isn't even near with what actual academics study.
