Nissan has been employing 6,000 auto workers at its plant in Smyrna, Tennessee since 1983.
I think you forgot about the maquiladora plants in Mexico that landed a lot of work that used to be done in the Midwest and although many southern states did lure in auto plants the fact is many communities were devastated after the factories left. That's why there was such a signifiicant exodus of people south from states like Ohio, Pa., Ill., etc.
