"As for the expected boon to the Mexican economy, we have seen none of these gains, and instead we have seen NAFTA's detrimental impact on the Mexican workers"

This quote by Stephen F. Lynch is describing the North American Free Trade Agreement (NAFTA) in between the United States, Canada, and Mexico. The contract was planned to benefit all 3 nations, however Lynch is recommending that the Mexican economy has actually not seen any of the anticipated gains. Rather, he believes that NAFTA has had a destructive impact on Mexican employees. This might be due to the influx of cheaper items from the US and Canada, which has caused a reduction in wages and task chances for Mexican workers. It might also be due to the fact that NAFTA has actually allowed US and Canadian companies to move their operations to Mexico, where labor is less expensive. Whatever the cause, Lynch believes that NAFTA has not been helpful to the Mexican economy.
