Free trade increases the prosperity of Americans – and citizens of all participating nations – by enabling consumers to buy more and better products at a lower cost. It promotes economic growth, efficiency, innovation and increased equity that comes with a rules-based system. These benefits increase with the increase in overall trade – exports and imports. According to economic historian Douglas Irwin, a common myth about U.S. trade policy is that low tariffs harmed American producers in the early 19th century, and that high tariffs then made the United States a major industrial power in the late 19th century.  An Economist of Irwin`s 2017 book Clashing over Commerce: A History of US Trade Policy notes: Truth and myth about the effects of open to trade The models used by Samuelson and Krugman to predict welfare losses and wage inequality are elegant, but simplistic, because they believe that products, factors and industries are homogeneous; that the factors of production within countries are mobile; and that the United States and developing countries manufacture similar products. In fact, most products differ in price and quality, production factors are often used for certain tasks and many products exported by developing countries are no longer produced in the United States. This also explains why the overall trade pressure on wage inequality in the United States is lessened. If the United States no longer manufactures certain products, lower import prices will benefit all consumers and will not affect relative wages.
The second, more serious issue is new generation contracts, the terms of which go far beyond traditional trade issues, as has already been said. These treaties present to the signatory states the limits of the economic policy framework. Since innovation depends on access to knowledge and the IP defines the conditions under which knowledge can be accessed and used (and who is paid for), international trade agreements that contain IP rules are de facto innovation agreements that de facto limit a country`s opportunities for innovation.2 Free trade has entered what the United States would become as a result of the American War of Independence. After the British Parliament passed the Prohibitory Act, which blocked colonial ports, the Continental Congress responded by effectively declaring economic independence and opening American ports to foreign trade on 6 April 1776. According to historian John W. Tyler, “trade was imposed on Americans, whether they like it or not.”  Debates on free trade and related issues, Ireland`s colonial administration, led at regular intervals (such as 1846 and 1906) to riots in the British Conservative (Tory) Party (Corn Law Issues in the 1820s to the 1840s, Irish Home Rule issues throughout the 19th and Early-20th centuries).
