We lost the textile industry in the deep south. We replaced it with auto manufacturing and parts suppliers. Kia in Georgia. Mercedes, Honda, and Hundai in Alabama, Toyota in Mississippi, and Volkswagen in Tennessee. I know Tesla is in Texas as well as a Ford or Chevy plant. I think there is a Toyota in Kentucky. All in non-union states, but providing jobs. Alabama is the most unionized state in the south, but it is a non requirement even if the factory votes to unionize. Also in Alabama is a Michelin tire plant and a BF Goodrich plant.
Alabama has union dock workers in Mobile, Steel workers in Birmingham (only one still operating), I think the tire plants are unionized. Also the power and gas utilities, as well as AT&T. There may be others, especially in the new largest city of Huntsville with rocket manufacturing and rocket engine manufacturing. Alabama still has a large poverty area of Southwest central Alabama where a the majority population minority lives, but everywhere else seems to be doing fine.
Alabama did go from the bottom 5 in high school graduation to the middle of the states by taking away drivers licenses of kids under 18 who drop out. Amazing what not being able to drive will do. Still have a problem with low IQ's of certain people, barely graduating.
