You aren’t paying a tax on a tax. You have a federal and state tax rate - they are two separate things, just like sales and property tax are separate (and you can’t claim sales + the others even now). It is ridiculous you were ever able to deduct for other taxes or mortgage interest in the first place.
So I presume you don't think businesses should be able to deduct expenses either.
In the case of taxes, how is it reasonable to tax someone on money they never even see? If you have no choice but to hand over 6% of your income to the state, shouldn't the state pay the federal income tax on that part if anyone does?
By your logic even if you never get the money you owe taxes on it. That really is ridiculous.
