The Toyota RAV-4 decision was made back in 2005. In don’t think education has improved in Alabama since. Also, IIRC, the higher Canadian wages were partially offset by not having to provide health benefits.
I cite it as I’m somewhat familiar with it as a friend and colleague worked for a supplier pricing out a in-region facility.
Alabama lost a Toyota plant to Ontario because literacy is so poor they would need to translate their documentation into Ikea-like pictograms.
