A 2007 study showed that nafta had “a significant impact on the volume of international trade, but a modest impact on prices and prosperity.”  Analysts agree that NAFTA has opened up new opportunities for small and medium-sized enterprises. Each year, Mexican consumers spend more on U.S. products than their counterparts in Japan and Europe, which means the stakes are high for entrepreneurs. (Most NAFTA studies focus on the impact of U.S. affairs with Mexico. Trade with Canada has also been improved, but the passage of the trade agreement has not had such a significant impact on the already liberal trade practices that America and its northern neighbour have complied with.) Much of the debate among political experts has focused on how to mitigate the negative effects of agreements such as NAFTA, including whether workers who lose their jobs are compensated or whether they are offering retraining programs to help them move into new sectors. Experts say programs such as U.S. Trade Adjustment Assistance (AAT), which helps workers pay for education or training to find new jobs, could help rebuke anger over trade liberalization. If the Trans-Pacific Partnership of Origin (TPP) were to enter into force, existing agreements, such as NAFTA, would be reduced to provisions that do not conflict with the TPP or require greater trade liberalization than the TPP.  However, only Canada and Mexico would have the prospect of becoming members of the TPP after U.S.
President Donald Trump withdrew the United States from the agreement in January 2017. In May 2017, the remaining 11 members of the TPP, including Canada and Mexico, agreed to pursue a revised version of the trade agreement without U.S. participation.  Edward Alden of CFR says the fear of trade deals has increased because wages have not kept pace with labour productivity, while income inequality has increased. To some extent, he says, trade agreements have accelerated the pace of these changes because they have “strengthened the globalization of the U.S. economy.” Removing trade barriers increases competition and lowers prices, increasing consumers` purchasing power. Removing trade barriers also expands access to products and services produced across North America, improving consumer choice.

in the United States, and Mabe and Modello in Mexico. This improved access to materials helps companies compete internationally, bringing benefits to the people of North America, such as employment. Many critics of NAFTA saw the agreement as a radical experiment developed by influential multinationals who wanted to increase their profits at the expense of ordinary citizens of the countries concerned. Opposition groups argued that the horizontal rules imposed by nafta could undermine local governments by preventing them from enacting laws or regulations to protect the public interest. Critics also argued that the treaty would lead to a significant deterioration in environmental and health standards, promote privatization and deregulation of essential public services, and supplant family farmers in the signatory countries. Thanks to NAFTA, Mexico has lost nearly 1.3 million agricultural jobs. The 2002 Farm Bill subsidized the U.S. agricultural industry up to 40% of the farm`s net income. When NAFTA withdrew tariffs, companies exported maize and other grain to Mexico at a cost. Mexican rural farmers couldn`t compete.
At the same time, Mexico reduced its subsidies to farmers from 33.2% of total farm income in 1990 to 13.2% in 2001. Most of these subventi
