The middle class is not going to give up its deductions on home mortgage payments and dependents, nor should they.
They certainly should. The mortgage interest deduction is a regressive deduction, and it drives up the cost of houses without increasing home ownership.
It is wealth transference of tax dollars to home builders and real estate agents. It is as fiscally unconservative as it gets.
All deductions, credits, and exemptions are government behavioral control programs which are paid for by higher tax rates and deficit spending. No sane, thinking conservative would ever support them.
You've been brainwashed by the people who are stealing from you. They have you believing you get to keep more of your money with deductions. It's a lie. You are paying higher tax rates because of them. You are not only not getting to keep more of your money, you are paying more than you would otherwise. Most of the benefits of tax deductions, exemptions, and credits are going to people wealthier than you, and you are paying for it.
Not only that, without any deductions you could fill out your taxes on a post card. And all those lobbyists would have no incentive to donate campaign cash to politicians to keep or create all those government gifts.
It's a $1.2 trillion annual boondoggle coming out of your hide, and the hides of your children and grandchildren.
