In its May 24, 2017 report, the Congressional Research Service (CRS) wrote that the economic impact of NAFTA on the U.S. economy was modest. In a 2015 report, the Congressional Research Service summarized several studies as follows: “In reality, NAFTA did not cause the huge job losses that critics feared, nor the significant economic benefits predicted by supporters. The overall net effect of NAFTA on the U.S. economy appears to have been relatively small, not least because trade with Canada and Mexico accounts for a small percentage of U.S. GDP. However, there have been adjustment costs for workers and businesses as the three countries have prepared for more open trade and investment between their economies. : 2 Nafta is the largest trade agreement in the world, with the three member countries declaring gross domestic product (GDP). Gross domestic product (GDP) is an indicator of a country`s economic health and an indicator of its standard of living.

more than $20 trillion. As part of the agreement, the three signatory states agreed to remove barriers to trade between them and increase investment opportunities for small and medium-sized enterprises (SMEs) that are defined differently globally by SMEs or small and medium-sized enterprises. The country in which a company operates supplies the United States, Canada and Mexico. NAFTA represents the North American Free Trade Agreement, negotiated by former U.S. President George H.W. Bush, which came into force in 1994 under President Clinton. The agreement exists between the United States, Canada and Mexico and was originally created to reduce trade costs and strengthen North American trade. The agreement eliminated almost all tariffs and taxes on imports and exports.
The agreement also frees the three countries from trade barriers. When the USMCA was first announced the day after the agreement, it was said that the agreement would eliminate the customs risks of goods worth about $1.2 trillion per year. A 2014 study on the impact of NAFTA on U.S. trade employment and investment showed that the U.S. trade deficit with Mexico and Canada increased from $17.0 billion to $177.2 billion between 1993 and 2013 and supplanted 851,700 U.S. jobs.  The agreement involved thousands of U.S. workers after U.S. companies relocated their production plants to Mexico to take advantage of lower wages and relax worker health and safety rules. In addition, according to critics, the agreement has led to environmental degradation due to rapid industrialization in Mexico.
Proponents of NAFTA in the United States stressed that the pact was a free trade agreement and not an economic community agreement.  The free movement of goods, services and capital did not extend to work.
