Marxism versus free market economies

Jordan Peterson explains why Marxism is stupid. There are Marxists in his audience. Watch and listen as they applaud Marxism's emphasis on bloody revolution at the 13-14 minute mark. Peterson ignores them. He just quietly nods his head up and down and goes on to his next point. Marxists believe that none of the proletariat will be compromised by their sudden access to power! Every time this dictatorship of the proletariat was tried, the proletariat proved to be every bit as corrupt as the capitalists! Marxists believe that the dictatorship of the proletariat will become so hyperproductive that utopia will be ushered in to the happiness and satisfaction of everyone! Capitalism produces inequality but it also produces wealth, and all of the other systems only produce inequality! The world's poor are getting richer than they ever have before.
