Paul Krugman has an article about Social Security today and, like virtually everything else published in the New York Times lately, it's all wrong wrong wrong. Fortunately, Just One Minute exposes Krugman's fallacies and contradictions. Does the man have any principals that don't shift from year-to-year and political party-to-political party? The Internet is forever, buddy.
If I could just add one other point to Tom Maguire's commentary: if you read the Krugman article, his call for expansion of Social Security is rooted in the infantalization of Americans and the liberals' role in salvation. Americans just can't be trusted to invest for their retirement, so we simply have no choice but to guide these poor souls through higher taxation and government intervention.
