NAFTA gave Mexico an edge; that does not mean Mexico's problems would disappear. Mexico's economic problems are the result of a low tax base and poor education, among other issues1. A trade agreement alone cannot solve a nation's complex socioeconomic issues. Though it is impossible to know what would have happened, it is fair to speculate that Mexico would import even fewer goods to the US if not for NAFTA. Therefore, even if Mexico has yet to become an industrial powerhouse, NAFTA can still be considered advantageous.  1 Joseph E. Stiglitz, "The Broken Promise of NAFTA," New York Times, January 6, 2004
