>This foreign-owned auto industry in the U.S. would be a nonunion industry, and largely southern. The Rust Belt would get rustier.
Why southern ? We have a number of "domestic" plants here in Ontario, Canada: Oshawa (Toronto), Windsor (Detroit). Also a Toyota plant in Alliston ?
My hometown of St. Catharines (Niagara Falls) was a big GM town back in the day. My friend made $20+ an hour as a tradesman in the 1980s while I was making $10 with a college degree. He called it "Generous Motors". Another friend told tales of taking his pillow to work on his summer job.
So far it's looking like GM may shrink back into the US, which makes much sense now that the Canadian and US dollar are within 2 percent of par.
I don't think I've heard the term "Rust Belt" in many years now.
Is the rust-belt now double rusted ? Reduce-able to powder with a light tap ?
