... the real problem here wasn't created by the changes coming with the new GOP tax plan. What we're seeing is the exposure of the massive, Democrat-driven tax burden on New Yorkers which had previously been disguised by a tax policy which allowed them to shove that burden off on the federal level.
If New Yorkers had been forced to actually pay all of these taxes themselves all along, they might not have gone along with Democratic pipe dreams for so many years. That's how the New York tax burden was able to become so massive to begin with. Who knows? With this stiff dose of reality, perhaps rather than fleeing the city or the state, the successful will be more prone to reject the tax and spend policies of the Democrats and try something new.
