The problem with the US car industry is that it has avoided making the strategic shifts it needed to make to survive in a world that is demanding more and more environmental friendly and energy efficient products. There is no use letting these companies remain alive in the long run if they don't change their strategies, and that's why, if the government wants to keep them alive, it must force them to make the necessary adjustments. Clearly they won't change by themselves, not only because they can't afford it (due to past mistakes) but also because of the inertia that the industry obviously possesses. Protectionism isn't a viable solution when your products stink.
