Liken it to a restaraunt where every meal ordered generates orders for (1) each, of a chicken breast, teaspoon of butter, potato, loaf of bread, plate, knife fork &spoon, and napkin.

I do understand their “just in time” no-overhead to store excessive inventory process. That wasnt what we were talking about though. I’m pointing out that Japan still manufactures a lot of the parts. They apparently value having some manufacturing jobs at home.
Theres another big nation that has a messianic cult that demands that their manufacturing sector be utterly dismantled.
