I think the David Brion Davis piece cited is collected in his new book, "<URL:http://www.yale.edu/yup/books/088140.htm > .
James Livingston and Martin J. Sklar are also great sources on capitalism and historiography ".Pragmatismand the Political Economy of Cultural Revolution, " and, "Pragmatism, Feminism and Democracy: Rethinking the Politics of American History, " Sklar, ""Capitalism and Socialism in the Emergence of Modern America: The Formative Era, 1890's-1916, " <URL: http://www2.h-net.msu.edu/~shgape/sklar2.html > , "The Corporate Reconstruction of American Capitalism, 1890-1916, " , " The United States as a developing country: Studies in US history in the Progressive Era and the 1920s."
T. Jackson Lears is also a good source.
