I joined the auto industry around 5 years ago. It blew my mind to some extent to be made aware that some ~25 years later, the effects of NAFTA are still to be fully realized. I had assumed that enough time had passed that any economic rebalancing would have been complete.
The potential is there and ripe for industry to whole cloth make the move to Mexico. My company for one is rumored to have an unwritten rule that they don’t do new construction in the US, despite being a US based company.
Only a few crown jewel US locations are really well managed and supported.
