Hurt Mexico and the jobs leave North America for Asia; here is a good quote from someone in the know at the end of the article:
"Speaking at Barclay's Global Automotive Conference in New York in December, Delphi’s chief financial officer Joe Massaro explained what he thought would happen to Delphi under several Trump trade scenarios.
If Trump were to close the border with Mexico outright, “in less than a week, all the people who voted for him in Michigan and Ohio would be out of work,” Massaro argued, underscoring the fact that many factories in the U.S., including car makers in Detroit, depend on parts made in Mexico.
If the United States were to withdraw from NAFTA and start taxing imports from Mexico again, Delphi would continue doing business in Mexico, he said. The company would pass on the extra cost to its suppliers or to consumers, or would find a way to reduce its production costs — which could mean layoffs or salary cuts in Mexico."
