One thing they can do is pay less state and local taxes.
And IF you say "move", then you have less than no idea how much that costs, that there is still the ObamaCare 3%TAX on the buyer & seller ( if you can even find a buyer in many areas of this nation ), and asking for a deluge of lefties moving into some now red states and turning then blue!
Should you come up with making your present state lower their taxes...then you are delusional at best.
And what do you tell people who have large families and are losing that deductible and to the divorced, who will no longer be able to deduct alimony payments? Kill most of your kids and remarry your ex?
Also, many states with lower taxes have HIGH property taxes which will either be capped at a $10,000 deductible or completely be done away with!
