NAFTA's effect on United States employment
The North American Free Trade Agreement's impact on United States employment has been the object of ongoing debate since the 1994 inception of the North American Free Trade Agreement (NAFTA) with Canada and Mexico. NAFTA's proponents believe that more jobs were ultimately created in the USA. Opponents see the agreements as having been costly to well-paying American jobs.
