I don't think there's anything inherently wrong with a bank being big. In fact, there are some good arguments about universality of geography that in theory, if you have all your eggs in one little community, and some big employer goes out, that could be your downfall.
There is a future for the auto parts industry, but it needs a consolidation and a rationalization of geography in that most suppliers have facilities in the U.S., although most of their customers are overseas.
