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 policy was a source of conflict in late 19th-century American politics. During the Civil War, Congress raised protective tariffs to new heights. This was done partly to pay for the war, but partly because high tariffs were popular in the North. A high tariff meant that foreign goods were more expensive, which made it easier for American businesses to sell goods domestically. Republicans supported high tariffs as a way to protect American jobs and increase prosperity. Democrats generally condemned them as a source of higher prices for goods, whereas the higher revenues that they generated for the federal government were not needed after the conclusion of the Civil War. Many Northern Democrats supported high tariffs, however, for the same economic reasons that Northern Republicans did. In the interest of party unity, they often sought to avoid the question as much as possible.
