I won’t deny that many many manufacturing jobs have gone overseas. A lot of this is due as much to over regulation and over taxation as it is to labor costs. However, your post addressed “auto” jobs. Off the top of my head I can not think of one car sold here that is made in “third world countries” by “slave labor”.
(Unless you want to count Mexico as third world, and then there are Dodge Pickups, and quite probably some GM and Ford products as well made there and sold here.)
