The document discusses the pros and cons of the North American Free Trade Agreement (NAFTA). It notes that NAFTA was established to improve the economies of the US, Mexico, and Canada by lowering tariffs and facilitating trade between the countries. However, it also discusses some negative impacts, such as real wages in Mexico falling significantly below pre-NAFTA levels while costs of consumer goods have risen much more than wages. The document argues that changes could be made to the treaty to reduce exploitation and achieve greater economic benefits for all countries involved.
