Never say never.
Communism did not work in specific societies at specific points along the evolutionary process forming their productive relations.
I'll say it again quite emphatically: Communism has always ended up in failure wherever it has been tried, and it always will. The Utopia it aims for is contrary to the fundamentals of human nature. It actually augments the worst of humanity in that it enables extreme concentration of power.
The breakdown of the capitalist mode of production is a historical inevitability. This thread is evidence that people are awake to the reality. Marx explained all of this that we are witnessing, and he did so scientifically by way of dialectic method. Communism is not a Utopia, it is the next step in the evolution of the social relations of production. The advanced development of our technology is going force us to make a decision, enslavement to the class that owns the technology used to produce the necessary requirements of life or freedom through a new social relationship of production.
Nonsense. Communism crushes individualism, creativity, and initiative. Compare economic output of the Soviet Union to that of the U.S. in the 80s.
And ultimately, the true test is the effect on human life. The Famines orchestrated by Staling and Mao resulted in 10s of millions of deaths due to starvation BY DESIGN.
The only intellectually and morally valid way to evaluate a human system of living is what happens to the quality and quantity of human life...at the individual level. Totalitarian systems don't value the individual, hence he is expendable to the serve the state. It's not a coincidence that the body counts of totalitarian regimes are enormous.
DEATH BY GOVERNMENT: GENOCIDE AND MASS MURDER
The communist societies of the Soviet Union and China bore no resemblance to Marx's historical dialectic materialist theory. A theory that is designed to improve the quality and quantity of human life.
The famines were the result of the underdeveloped industrial capacity of those societies, not Marx. Marx's theory takes into account the need for capitalism to first fully develop the means of production to such a degree that society will have no problem feeding the members of society.
Communism isn't something that needs to be forced on society by overbearing government. It arises naturally out of the conditions of present society. Like the condition that is being discussed in this thread.
"Communism is for us not a state of affairs which is to be established, an ideal to which reality [will] have to adjust itself. We call communism the real movement which abolishes the present state of things. The conditions of this movement result from the premises now in existence." Karl Marx
