How do the 40 percent of displaced manufacturing workers who don’t find new jobs survive? The short answer is that many became destitute and applied for disability benefits. Disability rolls shot up starting in 2000, rising by 3.5 million, with the numbers increasing dramatically in Ohio, Michigan, Pennsylvania, and other manufacturing-heavy states. In Michigan, about half of the 310,000 residents who left the workforce between 2003 and 2013 went on disability. Many displaced manufacturing workers essentially entered a new underclass of government dependents who have been left behind.
