The statement that is NOT an economic impact of free trade agreements in North America is:
"Mexican businesses have relocated to the United States where labor costs are lower."
This statement is incorrect because generally, businesses do not relocate to areas with higher labor costs; rather, they often seek to relocate to areas with lower labor costs. Thus, the relocation of Mexican businesses to the U.S. due to lower labor costs is not an accurate depiction of the impacts of free trade agreements.
