@Cycloptichorn,
You are hopelessly confused; have several important facts wrong, notably including the current top Federal tax rate; and are quoting me as saying things I didn't say.
The state tax bill doesn't change at all in either scenario.
The Federal taxable income in reduced by the amount of the state tax paid in both scenarios.
Our millionaire will save some money on his constant state tax deduction with the new 70% federal marginal tax rate by an amount roughly equal to the difference in the new and old Federral rates times the magnitude of his state taxes - this works out to about 3% of his income. This appears to be the point you are fixated on.
However, 2/3rds of our millionaire's income will now be taxed by the Feds at 70% instead of the current rate, and that will amount to about 21% of his gross income. This is the point you are ignoring.
At these confiscatory tax rates, our millionaire's post tax income will be significantly increased by the move to Nevada.
Seeing this requires a bit of algebra and some actual independent thinking (as opposed to plugging some incorrect numbers into Turbotax, and getting your opinions from websites). You might wish to try it sometime.
