I’m not sure what unions played directly in the city of Detroit’s BK. But unions (and the inflexibility they caused) were a BIG part of reducing the U.S. auto industries ability to compete with Japan. If the auto industry in Michigan were run like Silicon Valley with NO unions, things may have turned out very different. Silicon Valley has NO unions and this is a big reason why the U.S. is still #1 in much of high tech and still makes some of the best high tech products and software. The U.S. certainly does not make the best cars and has not for 25-30 years.
