The majority of the auto factory jobs that were (e.g. automotive assembly line work) are considered unskilled work; not even semi-skilled; never mind high-skill.
I rather think the point is that outsourcing of those jobs was proof of the assertion that unskilled manufacturing jobs at $30/hr (in 2022 money) plus rich benefits are not a thing that was sustainable.
Go ahead and re-read the comment you are defending. I think it has twisted in your memory to something much more reasonable rather than something that can be verifiably fact-checked as false.
