—Economies bounce back from job loss.—
Technically that’s true. But better the jobs be well-paying manufacturing jobs than low-skilled service sector jobs in fast-food, retail etc. Those jobs don’t really produce anything tangible, and in the case of retail jobs, merely sell goods produced overseas (especially China).
Let's make all our gym shoes in America. Those are gonna be some high-skilled, high paying jobs sewing those things together. While we're at it, we need a good domestic plastic lawn flamingo industry in America.
If those ever get cut off in time of war, we'll never be able to make them here. Once the skills are lost, they're gone for good.
