In 2012, textile and apparel exports were $22.7 billion, up 37 percent from just three years earlier. While the size of operations remain behind those of overseas powers like China, the fact that these industries are thriving again after almost being left for dead is indicative of a broader reassessment by American companies about manufacturing in the United States.

...

But as manufacturers find that American-made products are not only appealing but affordable, they are also finding the business landscape has changed. Two decades of overseas production has decimated factories here. Between 2000 and 2011, on average, 17 manufacturers closed up shop every day across the country, according to research from the Information Technology and Innovation Foundation.

Now, companies that want to make things here often have trouble finding qualified workers for specialized jobs and American-made components for their products. And politicians’ promises that American manufacturing means an abundance of new jobs is complicated — yes, it means jobs, but on nowhere near the scale there was before, because machines have replaced humans at almost every point in the production process.

Take Parkdale: The mill here produces 2.5 million pounds of yarn a week with about 140 workers. In 1980, that production level would have required more than 2,000 people.
