As I said, it's complicated.
First off, there are many states that don’t have a state income tax like Florida, Nevada and Texas that do much better than the high tax states. Drive around NY and CA, how do those highways and bridges look. Come down to Fl and TX and drive our highways.
Florida, Nevada and Texas "do much better"? How? Why? Those are the two questions. First - Florida doesn't have snow or mountains. That might contributed to the "highways and bridges" being better than NY. I can't say I've ever heard that California has highway or bridge problems. Also, many "highways and bridges" are subsidized by the federal government anyway (I believe the interstate system is). Texas is blessed with oil money, and Nevada with gaming money.
Even if you are correct, there are exceptions that make the rule. State-based infrastructure like mass transit, connectivity, recreational facilities (parks, etc.), has contributed to the creation of great wealth centers in NY and CA. Those people pay more in taxes to the federal government. It actually benefitted the zero tax states to have people flock to the attractive states like CA and NY and contribute more in taxes to subsidize the lifestyle of Floridians and Texans.
And were does the Federal Government get the money to return to the states. From taxes. So the high tax states can subsidize their budgets by its citizens getting a write off on that money spend in the state. How does that help the citizens of Fl and TX.
You are barking up the wrong tree here. Citizens of NY and CA contribute more to the federal government than they take out. That's pretty well-known, but I can get that data for you. I believe TX is a net contributor as well. If TX wants more money from the Federal Government, it should look to the net-takers, not NY and CA.
You are on the losing side of this and wealthy people in NY and CA are voting with their feet. Your budgets will be overwhelmed particularly when the socialist politicians decide to impose a wealth tax in NY and CA to pay for all their new spending programs.
I'm not sure what you mean. I'm from Indiana. I was explaining why the old SALT deduction was not necessarily unfair. It is very likely that the elimination of the SALT deduction will cause wealth to leave NY and CA. My question is whether it is a good thing that the new tax law forced that to happen.
