I always find these post funny because when people think manufacturing they think of simple assembly line work, or just running machines and packing up boxes all day. Those jobs are absolutely filled, and most of the workers are part time retired or just old people.
After that you have mid level cnc up to high level cnc work that happens in job shops and require teams of people in the 110-130 iq range to get stuff together quickly, designed, programed, set up and produced, in order to secure a nice margin on the job. These jobs are tough, underpaid, and cannot, absolutely cannot be done by beaners, even the Chinese are known for pumping out 50,000 parts loads without quality controlling through out the process, and shipping unusable crap. For a brief moment there it was cheaper to import shitty Chinese parts and fix them, but that ended under the first trump administration. I've even seen work get shipped to Mexico, then come back because they couldn't even master filling a plastic mold correctly. Something that takes an average American around 2 months to master. Believe me guys, when the boomers all retire (3 years to go), expect care parts to go to 8 week lead times, among many, many, many other things.
