"What's your solution to the supposed bullet-deficit in this country?"
Blasphamy is my solution, (at least in the eyes of a free marketeer).
The #1 job of the government is national defense. If the government can't defend us, it's failing. Relying on outside agents for basic military supplies is not providing for the national defense.
In the case of bullets, and other military essentials, subsidize. If capacity exceeds production requirements, "mothball" the capacity, don't scrap it, or sell it to China, (India, Singapore, etc).
Okay. But the super-specialized defense industry is really completely different from the rest of the manufacturing sector. There are valid complaints about how the gov't is handling defense procurement, but that really has nothing to do with the rest of our manufacturing.
