In his New York Times column today David Brooks cites data showing that populist fears that free trade is destroying American manufacturing jobs are unfounded:

The chief force reshaping manufacturing is technological change (hastened by competition with other companies in Canada, Germany or down the street). Thanks to innovation, manufacturing productivity has doubled over two decades. Employers now require fewer but more highly skilled workers. Technological change affects China just as it does the America. William Overholt of the RAND Corporation has noted that between 1994 and 2004 the Chinese shed 25 million manufacturing jobs, 10 times more than the U.S.

The central process driving this is not globalization. It’s the skills revolution. We’re moving into a more demanding cognitive age. In order to thrive, people are compelled to become better at absorbing, processing and combining information. This is happening in localized and globalized sectors, and it would be happening even if you tore up every free trade deal ever inked.
