As was the case in 2009 and 2011, keeping manufacturing jobs from leaving the country is Americans' single-most-popular approach for creating (or, in some instances, retaining) U.S. jobs. The idea clearly predates Trump's presidential campaign but gives some insight into why his message resonated with many voters.
Many economists and policy professionals express skepticism that the number of manufacturing jobs can expand significantly in the U.S. Some reasons that a substantial expansion of manufacturing jobs in the U.S. is unlikely include the difference between U.S. and overseas labor rates, the vast manufacturing infrastructure already in place overseas, and the growing use of robots and technology in place of workers at many manufacturing plants, wherever they are. Trump hopes to prove these prognosticators wrong.
