The US can't even make a smartphone any more. Or electrical distribution equipment. Or telephone central offices. Or TV sets. Next to go, cars. (Chrysler just exited the car business. Minivans only now.)
Well they are trying. Purism has a "Made in America" phone: the Liberty Phone.

Why do you think cars are leaving the US? Tesla is a fully American manufacturer with some of the most US sourced components, GM/Ford aren't moving their cash cows out of the country anytime soon. and the Japanese and Germans are expanding their presence in the US. You cited a long declining brand that has had an agism problem. Thats your best evidence? I guess you can make the argument that there are too many brands in the car industry but the car manufacturing sector in the US is still quite strong.
