You're talking about people who aren't ultra wealthy there. Once the tax bill gets high enough relative to elsewhere it doesn't make sense not to jump through the hoops to change your place of residence.
Once you are ultra-wealthy you don't need to worry about taxes unless you are so greedy as to make earning infinite money your only goal in life even if it hurts you in every other way. And it is silly to set general policy based around how irrational and neurotic individuals will act.
