For much of the past 30 years, the American public’s view of manufacturing has been unrelentingly grim: shuttered factories, laid-off workers and the steady disappearance of “Made in America” products from consumers’ shelves.

But U.S. manufacturing is showing strong signs of rebirth. Since the end of 2010, U.S. manufacturers have added more than 730,000 jobs, and industry analysts predict that the sector could see as many as three million new job openings over the next 10 years.

Now, however, American manufacturers are dealing with another kind of bad news: Even as industry’s prospects have recovered, its image has not. Americans still think of factory jobs as dirty, dangerous and offering little job security.
