From a 1988 speech:
Here in America, as we reflect on the many things we have to be grateful for, we should take a moment to recognize that one of the key factors behind our nation's great prosperity is the open trade policy that allows the American people to freely exchange goods and services with free people around the world. The freedom to trade is not a new issue for America. In 1776 our Founding Fathers signed the Declaration of Independence, charging the British with a number of offenses, among them, and I quote, "cutting off our trade with all parts of the world," end quote.
And that same year, a Scottish economist named Adam Smith launched another revolution with a book entitled "The Wealth of Nations," which exposed for all time the folly of protectionism. Over the past 200 years, not only has the argument against tariffs and trade barriers won nearly universal agreement among economists but it has also proven itself in the real world, where we have seen free-trading nations prosper while protectionist countries fall behind.
