Historians, James Huston notes, have been baffled by the role of high tariffs in general and have offered multiple conflicting interpretations over the years. (Low tariffs, all historians agree, were noncontroversial and needed to fund the federal government.) One school of thought says the Republicans were the willing tools of would-be monopolists. A second school says the Republicans truly believed that tariffs would promote nationalism and prosperity for everyone along with balanced growth in every region, as opposed to growth only in the cotton South. A third school emphasizes the undeniable importance of the tariff in cementing party loyalty, especially in industrial states. Another approach emphasizes that factory workers were eager for high tariffs to protect their high wages from European competition.
