NAFTA

from an economic perspective, NAFTA is a success. Without it, the United States would not be as strong a competitor with the European Union or China. That's critical now that both of these trade areas rank above the United States as the world's largest economies.

The increased trade was sorely needed after the 2008 financial crisis. Even more people would be unemployed without NAFTA.

N.A.F.T.A quadrupled trade between Canada, Mexico, and the United States.

 (That's because the agreement eliminated tariffs.) Trade between the three countries increased to $1.14 trillion in 2015.

Second, greater trade increased economic output. NAFTA boosted U.S. growth by as much as 0.5 percent a year. Three industries benefited the most from increased exports. They were agriculture, automotive, and services such as health care and financial services.

N.A.F.T.A  was the cause of stronger growth created jobs. U.S. exports to the other two countries led to almost 5 million new American jobs. In NAFTA's first four years, manufacturers created 800,000 jobs. Thats why the united states should participate in NAFTA
