I don't really agree with that. The auto industry has vast over capacity, and it's not just employees.
The Big Three companies (not the industry as a whole) have lots of excess capacity -- mainly because they operate under a dysfunctional business model which makes them uncompetitive in the marketplace but at the same time makes it more expensive to cut production than to maintain current production levels.
Its alright. If we can convince the French to allow more Muslims to burn more cars, the auto industry can step up to the challenge. Besides, what are the French going to buy? Peugeots?
