As the article linked above speaks to, GM (and probably Ford and maybe Chrysler) are making cars that are up to Japanese snuff. Somehow there's a jingoistic notion in America (it's most redolent in Detroit) that now that that's so, the domestic automakers have redeemed themselves and should once again ascend to market domination.
About a trillion things are wrong with this argument. I'll focus on three.
1. The Past. GM and the rest of Detroit have had, for at least the last fifty years a "may the customer be damned" attitude. Planned obsolescence. Lack of quality. Lack of innovation. And perhaps most egregious, franchised dealer networks that kicked the shit out of customers coming and going--ripping them off in every way possible.
2. False Patriotism. Since the 1960s rise of VW and then the onrush of Japanese autos into our market, Detroit has bludgeoned consumers with the notion that it's un-American to buy a foreign car. This is so contrary to logic and any notion of a free-market. Consumers have a right to buy the best product they can with their money. To impugn their patriotism is the worst form of bullying, abuse and dishonesty.
3. Lack of innovation. Detroit continues to be dishonest about its commitment to either decent fuel economy or pollution controls. They are quick to trumpet the few hybrids they do build and the few micro cars that get "world-class" gas mileage, but in point of fact, they are still pushing gas guzzlers and lag way behind Japanese and German automakers in alternative fuels. What's more, Detroit's powerful lobbies have, to date, prevented the US Government from raising fleet mileage standards. This is to the great detriment of our environment.
Detroit may someday make the best cars in the world. But when you've lied and broken promises to consumers for the better part of fifty years, you must to more than merely fix your product and yourself. You must apologize and make good on previous bad behavior.
