The North American Free Trade Agreement (NAFTA) was created 20 years ago to expand trade between the U.S., Canada and Mexico. Its secondary purpose was to make these countries more competitive in the global marketplace. It has been widely successful in achieving this. NAFTA is now the largest free trade agreement in the world. Why, then, is NAFTA so severely criticized? Discuss the most successful achievements of NAFTA for the last 20 years (including what each country benefited?) and the shortcomings of NAFTA for the last 20 years (including what each country has lost as a result of NAFTA).
