There's been studies that found the rich don't leave a place due to taxes. I.E. California has one of the biggest economies in the world... http://minnesota.publicradio.org/features/2011/02/documents/...
Makes sense, if you’re already wealthy then you pick where to live based on where you want to live. Optimizing based on taxes seems cheap, I’d imagine they’d rather solve that by making more money. Plus it’s not like US citizens have much choice, they have to pay the IRS no matter where you live in the world forever. Nowhere to run, nowhere to hide haha.
Kansas has low taxes, but no one's dying to move there.
