I mean I'm not going anywhere due to taxes, only place I'd go is Canada if anything.
Culture is far more important to me than taxes.
Like the post responding to you points out, the people moving probably aren't high income college educated earners. Taxes do not bother me, I lead a decent life, can afford most things I actually want (which isn't much my last big purchase was a bracelet I got essentially at cost and that was like 2 years ago, I could actually sell it for about 2x my cost) , and my taxes aren't too terribly high since quite a bit of it is capital gains right now, and my lifestyle is exceedingly cheap (relative to usual).
