I think this was kind of the point of the thing that's changing things.Now if said parts are made here we get inflated materials costs (union steel workers and pensions) etc. etc. as well as the parts cost, because instead of the people making said parts used to get paid what $5 per hour? Now the ones making the parts will get $40. per hour
As a point of reference, when Ford used to make Tauruses in Atlanta, each car took 24 man-hours to assemble. That doesn't count all the supplier labor, of course-- they were just throwing assemblies into a chassis. But 24x40 is under a thousand bucks. Add benefits and you're probably 1600-1700.
I find it hypocritical to think I deserve one wage and the guys making the stuff I consume to make a lower wage.
Now if the materials costs are inflated because of convoluted logistics, emergency re-planning, working three shifts at one of the few remaining factories because supply chains are artificially shifting rapidly... that's inefficient.
