Implemented in 1994, NAFTA significantly increased trade, investment, and job creation between the U.S. and Mexico, while lowering consumer prices. However, it also contributed to U.S. job losses in some sectors (due to lower Mexican labor costs) and environmental concerns in Mexico (from relaxed regulations).
Key U.S. benefits: Trade rose from $142B (1993) to $265B exports/$346B imports (2019); investment grew; 1.3M U.S. jobs supported by trade with Mexico; lower prices (e.g., corn -40%).
Key U.S. drawbacks: Estimated 700K+ jobs lost in 1990s; trade deficit with Mexico; environmental degradation in Mexico.
Overall, NAFTA had a net positive economic impact but with notable distributional and environmental costs.
