MICHAEL BARONE: The Fall Of The Midwest Economic Model. “In 1970, the future seemed to belong to Michigan’s example of big companies and big unions. Not anymore. . . . In 1970, Texas had 11 million people. In 2010, it had 25 million. In 1970, Detroit was the nation’s fifth-largest metro area. Today, metro Houston and the Dallas-Fort Worth metroplex are both pressing the San Francisco Bay area for the No. 4 spot, and Detroit is far behind. Adversarial unionism is one reason the Midwest slumped. It turns out that the 1970 assembly line, with union shop stewards always poised to shut it down, was not the highest stage of human economic development.”
