A. There's a paper that says so, even, using New Jersey as a case study.
Unsurprisingly, they don't move for the same exact reason that libertarian ideology breaks down when it comes to "if you don't like the laws where you live, move somewhere else." People are tied to their home area, because of friends, family, jobs, schools, everything, and it's not so simple to uproot your life to go somewhere more amenable to your inclination.
B. When will the Democrats understand that Republicans aren't playing by the same rules and that their main goal is to take America back to 1880?
This paper examines the migration response to a millionaire tax in New Jersey, which raised the tax rate on top earners by 2.6 percentage points, becoming one of the highest rates in the country. Drawing on complete NJ state tax micro-data, we estimate the migration response of millionaires using a difference-in-difference strategy. The results indicate little responsiveness, with semi-elasticities mostly below 0.1. Tax-induced migration is higher among people of retirement age, people living off investments rather than wages, and potentially those who work (and pay tax) entirely in-state. The tax is estimated to raise $1 billion per year and modestly reduce income inequality.
