Manufacturing companies in the U.S. are the most productive in the
world. The National Association of Manufacturers reports that
businesses within this industry contributed more than $2 trillion
to the U.S. economy in 2012, an amazing 12.5 percent of the total
gross domestic product (GDP). This very important industry is
responsible for employing about 9 percent of the total American
workforce and supports an estimated 17.4 million U.S. jobs.
