People who refuse to study history are doomed to repeat it. The Nazis were one flavor of socialists and looked how well that turned out. The USSR was communist-flavored socialism and 70 years of bread lines until it collapsed. China avoided socialistic collapse by instituting state "capitalism", which is just another form of socialism. European socialism is breaking down. What is wrong with the United States economy is a direct result of Keynsian economics (another form of socialism). At what point do we look at history and say "Let's not go there"?

But no, every generation has to revisit this failed idea as if we are really too dumb to learn from history.
