I wouldn’t so much agree with that as I once would have.
Looking at both GM and Ford they own a lot of car and truck brands. I think if you are looking for a Chevrolet answer to a Corolla or a Ford answer, you’re probably barking up the wrong tree. On the other hand, there’s probably a KIA or a Saturn or a Mazda offering this is effectively made by the same company.
I think one of the problems the auto industry itself has had over the years is there are too many versions of the same vehicle. For instance, why must there be a Ford, Mercury, Mazda, and Lincoln version of a Ford Explorer? Heck, there’s even a Lincoln F150 today.
Worldwide, there’s no doubt that Ford has a plethora of small cars that it could turn around and offer in the US if the demand were there. It’s not been and hence the conversion of Lincoln which has traditionally been known as a luxury car maker to a truck and suv maker because that’s what the Lincoln consumer market demanded.
As far as making money, I haven’t known there to be too many years ever that one of the big 3 has ever reported a profit. Certainly not for Ford/GM/Chrysler in the last 4 or 5 years. I have never understood how they report loosing billions every year and stay in business.
