Block the borders!!! Those rich people are fleeing state high taxes. Yeah, right–it’s a myth.

I always have argued this is a myth. Here’s another bit:

Proponents of the tax flight myth argue that people intentionally flee states like New York and California for states like Texas and Florida due to a conscious desire to pay lower state and local taxes. They draw the conclusion that states can promote in-migration and economic growth by cutting income taxes for the wealthy or at the very least stopping tax increases. Mazerov’s research shows that these arguments are dead wrong. In a paper he wrote in May, Mazerov found that taxes have a negligible effect on interstate moves; most people (75 percent) cited new jobs or family obligations as the main reason for leaving their state in a 2013 Census Bureau Survey. Furthermore, the rate of interstate relocation has declined over the past few decades; only 1.5 percent of the US population moved between states in 2013. 69 percent of US citizens still live in the state where they were born, and there is no relationship between a state’s income tax rate and the proportion of native born residents.
