No one consults these graphs when evaluating job offers. A large majority of the US job growth during and after the pandemic has been in the south, and that probably does have something to do with the policies in the south vs the north. But at an individual level, no one pulls out charts like this. They evaluate the job offer, and consider things like cost of living, state taxes, weather, etc.
Most people don't have 100M in the bank. Most wealthy people are just regular millionaires, with regular 7 figure houses and regular lives. So even if you make a million per year, you have radically more spending power in the south vs a place like NYC, or SF, where all the wealth has historically been concentrated. But regular millionaires also tend to have portable, mostly remote jobs, and all the facts point to what the OP posted about, that they are moving into the sunbelt. Any way you cut it, it's an economically appealing proposition to the vast majority of people, including "1 percenters," and also happens to provide better weather, closer access to warmer and more beautiful beaches, etc.
