NAFTA is good for US. NAFTA eliminated tariffs and trade increased to $1.14 trillion in 2015. The prices on groceries are lower. Various industries also benefit from NAFTA such as agriculture, automotive, as well as services like health care and financial services. Jobs were also created -- about 800,000 jobs were created by manufacturers in the first four years of NAFTA's creation. Also, NAFTA decreases the US's reliance on the Middle East for oil.
