Are you arguing GM isn't better today than 4 years ago? Or are you actually not understanding that his reference to "Detroit" had nothing to do with the actual city and that he was referring to car companies. Yes, GM has a continued influence on the City of Detroit's economy. No, the City of Detroit isn't doing good. Yes, GM is much improved fiscally, as are other American car manufacturers. No, the fact that the City of Detroit is financial insolvent doesn't have anything to do with whether the US car companies are doing well or not.
