> We make plenty of stuff at scale
Maybe this video of a rather famous YouTuber trying to manufacture something as simple as a grill scrubber with a US supply chain would help you understand how bad it is?
One thing that struck me is seeing his months long struggle, where the only injection mold designer he could find was near retirement age and wouldn't be doing it for too much longer, the tool & die expert he talked to died between when he interviewed him and when he made the video, he had to deal with suppliers lying about where their parts came from, and some American suppliers could only provide low quantities without him paying to upgrade their tooling. Then there's a comment from someone in China saying that over there, he'd be able to bring his product to mass production in about 5 days in whatever quantity he wanted, and at a higher quality (more corrosion resistant metal, more durable silicone, etc).
I agree the situation is dire, but do not underestimate the US government’s ability to spend its way to gain a desired result. The first time a bullet hits US soil there will be 50 million people falling over themselves to manufacture shoes by hand if it helps “kill the bad guys”
