There it is in a nutshell - Endemic problems that caused business to leave our shores for greener pastures - And which of any of those problems has been fixed? (*none*)
So how is leading em back to the barn with a nose twitch going to work? The same problems for business here, remain. They are 'coming home' to the very same troubles that made em leave.
Fix the problems and they will come on their own.
Well, that''s why I mentioned Ross...That's when this started in earnest. Parts for 'American Made' cars were coming from all over. Even ERTL toys (die-cast cars, construction equipment, etc. --nice toys) moved South...and it seemed like a race for the border. NAFTA and its successsor agreements coupled with increasing environmental regulations, sometimes coming so fast that the last refit wasn't done before the next set of regs came out, made making things here difficult, if not impossible, if you were going to show a profit.
So business being what it is (not a charity), the shops were moved elsewhere. It's a self-inflicted wound. It may have benefited stockholders, but the guys who got the pink slip, sometimes whole towns full of them, were stuck hard. It hit the logging and lumber industry out your way, too. We all saw some version of it between the coasts in flyover country, and it took the shiny off what became the Rust Belt, too.
You're preachin to the choir 
... But go try and source parts for that old iron now.
Whip out your Google and look. You'd be surprised how many parts are being made new, from sheet metal to lights to engine parts. They likely cost more than you had in the vehicle when you bought it, but they are out there.
