Tariff
In contrast, in economic theory tariffs are viewed as a primary element in international trade with the function of the tariff being to influence the flow of trade by lowering or raising the price of targeted goods to create what amounts to an artificial competitive advantage. When tariffs are viewed and used in this fashion, they are addressing the country's and the competitors' respective economic healths in terms of maximizing or minimizing revenue flow rather than in terms of the ability to generate and maintain a competitive advantage which is the source of the revenue. As a result, the impact of the tariffs on the economic health of the country are at best minimal but often are counter-productive.
Tariff in United States history
Democrats were divided on the issue, in large part because of pro-tariff elements in the Pennsylvania party who wanted to protect the growing iron industry, as well as pockets of high tariff support in nearby industrializing states. However President Grover Cleveland made low tariffs the centerpiece of Democratic Party policies in the late 1880s. His argument is that high tariffs were an unnecessary and unfair tax on consumers. The South and West generally supported low tariffs, and the industrial East high tariffs. Republican William McKinley was the outstanding spokesman for high tariffs, promising it would bring prosperity for all groups.
