This map from the National Right to Work Legal Defense Foundation will soon be updated to include Michigan among the states where the scourge of unionism is held in check.
As you so rightly point out, in those regions where Big Labor is a non-factor, the economy flourishes, even under Obama's regime. In particular, the South has long cherished worker freedom and liberty by keeping a close eye on union racketeers. Without the crippling workrules, archaic regulations and confiscatory wages imposed by unions, American enterprise can indeed soar to great heights. It's happened here in Dixie, the economic engine of America, and now Michigan is poised to make the next advance.
