> I would love to hear an example of a successful communist state.

Basically, all of them

They were so successful that the west (meaning mainly the U.S. and the Brits) have invested gigantic amounts of resources in fighting them.

Imagine what they could have done for their citizens instead...

And yet, communist ideas are still alive and kicking, while capitalism is hated everywhere, not only by the people living in anti-capitalistic countries, but also by those living in capitalist countries and by several über rich capitalists, nowadays. Modern capitalism isn't market economy, it's not fair in any way, it doesn't promote growth nor it does empower the masses and all the successes attributed to capitalism, for example The Marshall Plan, were an implementation of socialists ideas under a different name.

Capitalism doesn't even improve living standards anymore, now that it distantiated itself from the socialist idea of the welfare state and promoted an unprecedented concentration of wealth and resources in the hands of the very few, who don't care about the society at large and have no problem in enslaving the people working for them.

The real problem that you can't see, because your brain has been programmed to not see it, is that the U.S.A. empire is the worst in the history of mankind and it showed all its cracks and flaws in less than a century.

Imagine how failing so hard and still claiming victory sounds to 90% of the world's population not brainwashed by the U.S. propaganda...
