Does free trade work? (event 1)

http://economyincrisis.org/content/free-trade-benefits-few This story argues that free trade is detrimental. To show this the consequences of NAFTA (North American free trade agreement) were looked at. This agreement caused massive job loss in both Mexico and the U.S. and only benefited the large corporations. These are some good points, but in the article the advantages of specialization are not shown. The people and resources that were working on corn production in Mexico can now be used for something else allowing more progress.
