Vale a pena ler o livro "Free Trade Under Fire", de Douglas A. Irwin.
"Despite widespread skepticism about free trade among public at large, economists generally take a positive view of international trade and believe that reducing government-imposed trade barriers is desirable. In the eyes of economists, trade between countries is usually mutually benefitial, just like the trade in goods within a country, even though the goods happen to cross national boundaries. While some groups lose from trade, at least temporarily, people around the world are generally much better off with trade than they would be without it".
