This document discusses economic integration between the United States and Mexico. It notes that NAFTA led to a tripling of trade between the countries from 1990 to 2008. While trade and economic growth were pretexts for NAFTA, the real goal was greater integration and potentially a North American Union similar to the European Union. NAFTA significantly increased GDP, GDP per capita, life expectancy, and reduced inequality in Mexico over its first 20-plus years. However, some view further integration as culminating in a North American Union, merging the economic and political systems of the three countries.
