The three great things which most signally marked the administration of Jackson were the debates on the tariffs, the quarrel with the United States Bank, and the Nullification theories of Calhoun. It would seem that Jackson, when inaugurated, was in favor of a moderate tariff to aid military operations and to raise the necessary revenue for federal expenses, but was opposed to high protective duties. Even in 1831 he waived many of his scruples as to internal improvements in deference to public opinion, and signed the bills which made appropriations for the improvement of harbors and rivers, for the continuation of the Cumberland road, for the encouragement of the culture of the vine and olive, and for granting an extended copyright to authors. It was only during his second term that his hostility to tariffs became a passion,--not from any well-defined views of political economy, for which he had no adequate intellectual training, but because "protection" was unpopular in the southwestern States, and because he instinctively felt that it favored monopolists at the expense of the people. What he hated most intensely were capitalists and moneyed institutions; like Jefferson, he feared their influence on elections. As he was probably conscious of his inability to grasp the complex questions of political economy, he was not bitter in his opposition to tariffs, except on political grounds. Hence, generally speaking, he left Congress to discuss that theme. We shall have occasion to look into it in the lecture on Henry Clay, and here only mention the great debates of Jackson's time on the subject,--a subject on which Congress has been debating for fifty years, and will probably be debating for fifty years to come, since the whole matter depends practically on changing circumstances, whatever may be the abstract theories of doctrinaires.
