"It is fragmented by design. By Congress.…"

That's only in peacetime. During WWII the Government directed US industry to gear up for war production and the transformation was not only remarkably swift but also the largest retooling effort in history.

In these fraught times it's worth revisiting that history to remind ourselves of what's actually possible. By today's standards, the US's industrial response to war was truly remarkable.
