The problem with corporations locating in red states isn't finding the generous tax giveaways or space, it's finding qualified talent and more importantly trying to convince current employees living in blue states to relocate to red states.
If you were a young exec with a family working at Amazon in Seattle, do you want to move your kids from great Seattle area public schools to schools so poor they can only go four days a week, where school boards overtaken by Xtian zealots don't believe in science and insist that intelligent design be taught with the same emphasis as evolution? I know that Boeing had that problem when they opened a line in South Carolina. Nobody with kids wanted to go to SC. I know Seattle has its problems, but compared to any red state, it's paradise!
One of the byproducts of the GOP's anti-education agenda is that companies have to go outside the country with H1B visas to find qualified employees. You look at engineering departments of major universities you'll see tons of kids on visas from India, China, etc. Those seats used to be filled by American kids, but the kids educated in red states can't compete anymore.
