Sound Policy? Probably not
In the article linked below, it notes that New York gets over half of its tax revenue from the top 2% of earners. Now they want to charge more tax. Like him or not Former President Trump moved his residence to FL partly to get away from the smothering taxes in NY.

I actually use this scenario as a part of my test questions when I teach tax at colleges.
