IS this not just a symptom of a maturing industry? At one point America had hundreds of automotive companies, those hundreds consolidated down to three. 100 years later, those three are still dominate. I'm not saying it's good or bad, but it sounds like something that has happened before and from that we can drive the discussion on weather this is good or bad, or something we can ignore.
