Defenders of high state taxes like to point out that surveys find few high-net-worth households move primarily to lower their tax bills. This may be so, but it misses the point: high-income, high-net-worth households don't move away from high tax states if they're getting fair value for their taxes. But if services and infrastructure are crumbling around them even as their taxes keep ratcheting higher, then the benefits of moving become much more compelling.
In other words, if you're getting good value for your high taxes, then high taxes are not sufficient motivation to move. The problem is not high taxes per se, any more than a high cost of living is the reason to move from a world-class city with great amenities: world-class cities with great amenities have always cost more than less desirable locales, even in the 1600s.
