Q. The North American Free Trade Agreement (NAFTA) was created 20 years ago to expand trade among Canada, U.S. as well as Mexico. Its secondary purpose was to make these countries more competitive in the worldwide market. It has been extensively successful in attaining this. NAFTA is at present 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).
