In 1993, it seemed obvious to me that NAFTA was about one main thing: providing a huge new (and much cheaper) labor force to U.S. manufacturers by making it safe for them to build factories in Mexico without fear of expropriation or profit-limiting regulation. But the Clinton administration claimed it would open a new market to U.S. business, and U.S. Trade Representative Mickey Kantor, President Clinton, and even Labor Secretary Bob Reich argued that it would create jobs for American workers and even increase job creation in the U.S. auto and steel industries. They said NAFTA would benefit Mexican workers and help create a bigger Mexican middle class, while deterring migrant workers from crossing the border to seek jobs in the United States with better wages. They also argued an alternative theory: that NAFTA would help keep U.S. manufacturers from moving to Southeast Asia, and that it was better to keep that off-shored work in our hemisphere and along our border.

What actually happened?

1. The trade balance with Mexico went from positive to very negative, resulting in the loss of more than 600,000 jobs in the United States.
2. Mexico’s corn farmers were overwhelmed by a flood of cheaper U.S. corn and almost 2 million agricultural workers were displaced. Most of them migrated illegally to the United States and remain here as exploited, undocumented workers.
3. Wages fell for Mexican industrial workers, to the point that autoworkers in Mexico now make less than Chinese autoworkers. Some Japanese carmakers start paying Mexican workers at 90 to 150 pesos per day, or $6 to $10.
4. U.S. auto companies shifted investment to Mexico to exploit its much cheaper labor. AP reports that “Mexican auto production more than doubled in the past 10 years. The consulting firm IHS Automotive expects it to rise another 50 percent to just under 5 million by 2022. U.S. production is expected to increase only 3 percent, to 12.2 million vehicles, in the next 7 years.” Since NAFTA’s enactment, employment in the U.S. motor vehicle and parts industry has declined by more than 200,000 jobs.

More recent claims about the expected benefits of free trade agreement with Korea have proven hollow, too. Instead of creating 70,000 jobs, the net effect has been a higher trade deficit and the loss of 60,000 jobs. Worse, the harshest impact of that deal won’t be felt for several more years, when protective tariffs on pickup trucks are eliminated, making Korean imports 25 percent cheaper than they are today. U.S. auto workers will be hard hit.

And then there’s Permanent Normal Trade Relations with China and China’s admission to the WTO, which led to an explosion of imports and the loss of more than 3 million jobs, mostly in manufacturing and mostly in occupations that paid more than the jobs created in exports industries.

One bad experience after another: that’s why so many are so opposed to fast track and more NAFTA-style free trade deals.
