United States automakers are key to United States national security. When American automakers build cars, they have to innovate and invent so that their foreign competitors do not create a better product than them. When they invent new things, they pass these things on to the government, which uses them to protect our country.
Although US automakers represent a significant portion of our GDP, employment, and national pride, they are not key to the security of the US as a whole. Because the US relies on a capitalist structure, if the automaker is not beating competitors, then it deserves to fail. If another country can make better cars than the US, then US automakers will have no choice but to adapt and improve, which will be good for our country as a whole.
