"From 1.5 to 3 million rural Mexican families have been driven out of business since NAFTA was implemented, according to the Resource Center of the Americas. We send our corn to Mexico, and it sends its people to us. The number of immigrants from Mexico decreased by 18 percent in the three years before NAFTA went into effect, says the Pew Hispanic Center. During the first eight years of NAFTA the annual number of Mexican immigrants increased more than 60 percent."
