Beyond national security or nostalgia, there's also simply the issue of skill and expertise. Factories are full of people actually working the tools, materials and processes. This is where generational experience forms— people learn a lot when they're actually hands-on. Tim Cook famously said they don't manufacture in China because of the low labour cost, but the quantity of skill (specifically, in the case of Apple, with advanced tooling and materials) [1].
This skill becomes innovation, quality, etc. and before you know it you're not inventing and designing devices for other people to build. You're buying devices designed, invented and built somewhere else.
I would also note that admiring and romanticizing capital over labour IMO is common in the USA than in other countries. I'd guess it's because the rest of the world saw some level of marxist influence that led to the formation of still-existing labour parties in the least, while the USA prosecuted marxism pretty strongly. Beyond how effective this marxist wave actually was in achieving better conditions for laborers, I'd say it at least did generally lead to ideological effects.
The general ideas that there's dignity in all work, that any job should pay a living wage, that money isn't the end all, that laborers deserve recognition, etc— I've noticed all those to be more prevalent outside the USA. Admiring people who make a lot of money with little work, or not working and living off rents, or wealth irrespective of the means to achieve it, etc— I've noticed that moreso in the USA.
So overall, you're right— I'm sure a lot of people in the USA wont actually want those jobs with how little protections labour has and how much people admire earning good money with little effort. Though nonetheless, I also believe there's a sector of the population —perhaps not in HN— that would appreciate those jobs.
