Nonsense.
Tax deductions are written to encourage certain behavior or discourage certain behavior.
Which is not what taxes are supposed to be for, taxes should be for funding the government. nothing more, nothing less
What is that based off of?
In America there are no Constitutional restrictions on taxes as far as the states are concerned; it's a state's rights issue; only the Federal Government has enumerated purposes.
The Federal Government is not allowed to do ANYTHING.... except the enumerated purposes. Do you see anywhere in the constitution that says the Federal Government is allowed to reward some, and punish others, for politically acceptable choices?
No, sir. You do not. Therefore, there is no need for a constitutional restriction. Everything is restricted, except for the specifically enumerated powers given to the Federal Government.
As for state rights, I have no problem with that. I think we can debate that, and I would debate that taxes should be used only to fund the state government, and the duties we decide our state should engage in.
But if you want your state to reward and punish with taxes, that's between you and the people of your state. I have no problem with California beating the crap out of the poor with taxes, and giving deductions to all the wealthy elites that live there, because it's their state, and they voted for those idiots, and they are getting exactly what they deserve.
But again, on the Federal level, no. There is no provision in the constitution that says the Federal government can do any of that, and thus it is wrong, unconstitutional, and they are prohibited from doing it. The entire tax code should be tossed out, burned, and replaced with an absolute flat universal tax, that applies to absolutely everyone equally, rich or poor no deductions, no nothing. You should do your taxes on a 3X5 card... name, social, income, multiply by 0.1... pay tax, done.
