I didn't read him the way others seem to have, that he himself prefers socialism. I read that he thought socialism might be the end result of capitalism failing, as Marx had written, and that such a probability not only still existed but was growing larger.
I respectfully disagree. If anything, and to the bane of liberals (or so-called progressives) everywhere, socialism has
already proven that it is a miserable failure. This is The Left's blind spot, just as religion is The Right's blind spot. Socialism has long been shown in theory to be unworkable. And every attempt to seriously practice it, without compromising to Capitalism to actually get things done, has turned out to be a monstrous failure over the last 100 years. The list of failures is real and the body count worse than anything one might imagine (except, of course, for the body count tallied by religion over the centuries). Lenin, Stalin, Pol Pot, Mao, Castro, Kim Il Jong, Ho Chi Minh, and a dozen less notables including the latest thug, Chavez--these men and their socialist/communist regimes (pure Marx) actually killed over 100
million people, and destroyed the productive lives and spirits of a billion more. For generations. (Imagine having been born in the Soviet Union in the 1930's. Your life, your dreams, was effectively a big zero.)
No, socialism is already dead; it's just that some people (who ironically refer to themselves as progressive, intelligent, and elite) either don't or refuse to see what's obvious yet. If this mixed economy we have in the United States mutates into something other than Capitalism (and I agree with Nitro that we do have our problems to solve), it certainly won't turn into the system that powers the lights in North Korea these days.
