TN does not have a state income tax, and no longer taxes interest/dividend income either. Cost of housing is about an order of magnitude lower. Property taxes are lower. For the most part a radically lower population density. If you cross the Atlantic a lot, you don't have to spend 6 hours crossing North America first. If you're inspired to make The Handmaid's Tale a reality, don't like a whole lot of racial diversity, and love you some guns, TN and a majority of its population are friendlier to you.
