To the Editor:

American families devastated by the outsourcing of manufacturing jobs and lower wages would be dumbfounded by Eduardo Porter’s March 30 Economic Scene column, “The Jobs Nafta Saved.”

Germany, Japan and other countries continue to have strong domestic auto industries while also paying livable, middle-class wages. American corporations take advantage of the North American Free Trade Agreement’s extraordinary investor protections, weak labor standards and low wages to outsource hundreds of thousands of jobs.

A fourth of American manufacturing workers make less than $11.91 an hour. America is in a vicious cycle pitting American wages versus the threat of jobs moving to Mexico at lower wages. Mr. Porter neglects to discuss why wages are so low in Mexico. Company unions there are more aligned with employers than with workers. Repressive policies keep Mexican workers from organizing in a meaningful way, maintaining wages and working conditions at very low levels, as the United States State Department’s Mexico 2014 Human Rights Report concludes.

Apologists for Nafta often support the Trans-Pacific Partnership. Yet even TPP advocates project that the manufacturing trade deficit will increase by over $55 billion and produce 121,000 fewer manufacturing jobs by 2030.
