The SmarterEveryDay piece was disheartening for sure, echoes what I have been singing from the rooftops ever since the government dropped the USA origin of manufacturing requirements for all purchases. Sure, it was a kind of corporate welfare, and it made for a tricky incentive misalignment, but it kept a lot of strategic industries on life support. We would be in a way, way better position now if it hadn’t ended.
All our military work still uses US electronics shops and machine shops.
At this point I think in practice it’s a preference for US manufacturers but a long way from robust enough to establish domestic supply chains.
Also -a lot- of military purchases are local, discretionary on a credit card, and there is no oversight on the origin there- it’s whatever they need from office max or the hardware store.
SmarterEveryDay attempted to make a grill scrubber in the US. https://www.youtube.com/watch?v=3ZTGwcHQfLY
tl;dr He did it, but it went very poorly.
