The meat industry was one of the most affected agricultural sectors. In 2004, Mexico moved from a small player in the U.S. export market to the second largest importer of U.S. agricultural products, and NAFTA may have been an important catalyst for this change. Free trade has removed barriers to business between the two countries, allowing Mexico to offer a growing meat market in the United States and increase sales and profits for the meat industry in the United States. A simultaneous and dramatic increase in Mexican GDP per capita has significantly changed meat consumption patterns due to increased per capita meat consumption.  Supporters supported NAFTA because it opened up Mexican markets to U.S. companies like never before. The Mexican market is growing rapidly, which promises more export opportunities, which means more jobs.
However, proponents have struggled to convince the American public that NAFTA would do more good than harm. Their main efforts have been to convince citizens that all consumers have as wide a choice of products at as low a price as possible, which means that consumers would be the main beneficiaries of lowered trade barriers. The U.S. Chamber of Commerce, which represents the interests of small businesses, was one of THE most active supporters of NAFTA and organized small and medium-sized business owners and employees to support the agreement. This support was essential to counter the efforts of organized work to put an end to the agreement. "The USMCA will provide our workers, farmers, ranchers and businesses with a quality trade agreement that will result in freer markets, fairer trade and robust economic growth in our region. It will strengthen the middle class and create good, well-paying jobs and new opportunities for the nearly half a billion people who call North America home. The debate on the impact of NAFTA on its signatory countries continues. While the United States, Canada and Mexico have experienced economic growth, higher wages and stronger trade since nafta, experts disagree on the extent to which the agreement has actually contributed to these benefits, if at all, to manufacturing employment. , immigration and consumer goods prices. The results are difficult to isolate and other important developments have occurred on the continent and around the world over the past quarter century. The kick-off of a North American free trade area began with U.S.
President Ronald Reagan, who made the idea part of his campaign by announcing his candidacy for president in November 1979.  Canada and the United States signed the Canada-U.S. Free Trade Agreement in 1988, and shortly thereafter, Mexican President Carlos Salinas de Gortari decided to address the United States.
