According to Prof. Don Boudreaux, free trade is nothing more than a system of trade that treats foreign goods and services no differently than domestic goods and services. Protectionism, on the other hand, is a system of trade that discriminates against foreign goods and services in an attempt to favor domestic goods and services. In theory, free trade outperforms protectionism by bringing lower cost goods and services to consumers. In practice, the benefits of free trade can be seen in countries like America and Hong Kong. Both countries have a relatively high degree of free trade, and, as a consequence, have experienced an explosion of wealth.
