Jefferson Cowie and Nick Salvatore have written an ambitious and provocative essay. Ranging across more than a hundred years of history in less than half as many manuscript pages, it seeks to unlock deep secrets of the American past. The New Deal, Cowie and Salvatore argue, constitutes a lone “long exception” in a history otherwise determined by “a deep and abiding individualism” so definitive of U.S. political culture that it dooms any radical rupture in advance. Presenting themselves as realists, Cowie and Salvatore claim that their interpretation of the long sweep of national history “can provide a more stable intellectual foundation on which to build discussions of present and future politics.” I disagree, and the reasons why matter.
