When we talk about what the end of the U.S. auto industry will mean to thousands of autoworkers, we tend to have a specific image of that worker in mind: He’s a conservative white Democrat who lives in suburban Detroit, hangs out in his local union hall, belongs to a bowling league and owns a hunting cabin in the Upper Peninsula. This is the iconic American autoworker. In fact, as much as a fifth of the industry’s work force is African-American.
