Correct me if I'm wrong, but you're complaining about a potential tax change which would see your personal taxes going up but someone in Texas going down?

If it is revenue neutral at the federal level after removing the deduction, the implication is that the overall federal rate drops accordingly - you suffer only because your state taxes are higher (and what you lose from that deduction you don't gain from the lower tax rate) and because the present system contains a distortion, not because the proposal is unfair.
