This chapter turns again to David Potter, who argued compellingly that American exceptionalism emerged neither from a practical, nonideological political genius nor a prevailing faith in an inherited ideology, but rather from the influence of widespread and enduring economic abundance on the American character. Potter’s People of Plenty argued that the broad availability of abundance became the nation’s single most defining characteristic. Potter’s argument proved especially convincing during the broadly shared prosperity of the post-World War II years. Yet Potter’s explanation never quite accounted for the enduring postbellum poverty of the American South that lingered long enough for President Franklin Roosevelt to label the South the “nation’s no. 1 economic problem” in 1938. Additionally, as the nation’s economic growth slowed significantly and inequality worsened since 1980, there are new reasons to question whether Potter’s argument can remain influential if growing economic inequality and the related class anger persists or worsens.
