Ever wonder why no new U.S. car companies have been started up over the past couple of decades? And I'm not counting small shops that are custom building supercars for the super rich or subsidized electric vehicles for the eco-minded.

It also tries to explain why the major car companies are more than happy to let Uncle Sam literally have a seat in their boardrooms.
