This is really sad. Krugman is a professor at an esteemed US college. He has to know that there is not one example, either today or in history, of successful socialism on a large scale. It has failed everywhere it has been tried and one need not look farther than across the pond to see how it has made Europe almost irrelevant. Europe is a continent where businesses sell to one another. No grand innovations on a global scale ala Microsoft, Boeing, or even Walmart. He reaches a wide audience and is beloved by leftists across the country. Go figure.....
Ask Mr Krugman why poverty was at 14% in 1964 and is at 14% in 2011. He cannot educate his butt out of that one.
