One of the primary concerns in the United States about entering into the North American Free Trade Agreement (NAFTA) was that sub-standard products manufactured in Mexico would be imported and sold in the United States. U.S. jobs would be lost to Mexico because wage rates in Mexico were so much lower than in the United States. U.S. revenues from import tariffs would be reduced. the agreements between the United States, Canada, and Mexico would violate the most favored nation (MFN) principle of the World Trade Organization (WTO).
