Hyundai and its sister company, Kia, which opened a plant last year in Alabama, have brought thousands of well-paying jobs to the region and even helped nurture a little Korean culture in Montgomery, the first capital of the old Confederacy. Hyundai is running its Montgomery plant almost nonstop. Rarely do more than a few weeks pass without word that another parts supplier has dozens of new positions to fill, typically offering good benefits and double the pay that the average Alabaman earns.
