Small-Scale Question Sunday for April 20, 2025

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

I’m inclined to think that “jobs” is just, in democracies, the politically optimal phrasing to accomplish what nations really want, which is adversary-proof production of food and materiel.

My question is about the physical goods manufacturing, and is to do with, for example, how many steps of the process of car manufacturing can you, hypothetical power of a country, get within your borders and how should you go about it if tariffs are in your tool chest? Lights-out factories are totally fine.

As many as you want? Forget tariffs; you can just ban stuff from foreign. The biggest constraint would be if you're not a large enough country to be able to develop all of the specialization required (while also accomplishing all the other things a country needs to accomplish).

how should you go about it

One needs a metric for "should". Sure, North Korea now "produces" its own airplanes. Which I guess is cool if you want to make sure that you have whatever metric of "adversary-proof" (I'm not convinced it actually is, but it depends highly on the metric you use) and if you're okay with only being able to produce what are essentially copies of extremely old Cessnas. Maybe in 50 years, they'll be able to produce their own WWII-era fighter jets, which I guess is "adversary-proof" to one metric, but probably not all that "adversary-proof" according to other metrics.

I kind of joke, but only kind of. Market size is a significant factor in the diversity of goods that are going to be available and how 'advanced' they can be, because diversity and 'advancedness' requires significant specialization. Thus, if we're shutting off large chunks of the market because we don't trust them, we're necessarily going to take hits elsewhere. Where you "should" be on this tradeoff curve is extremely dependent on how you've defined "should" in the first place.
