It won’t ‘soak’ anybody. Just lower your state taxes a bit to offset the loss of being unable to deduct them. Expecting low tax states to subsidize high tax states is Robin Hood in reverse.
Sure it will. That’s why many GOP House members, including mine, are against eliminating the deduction. And it also will tax the hell out of the middle class in order to “pay for” slashing the corporate rate. Even the Ways and Means Committee outlined this.
Lower tax states do not “subsidize higher tax states.”
In fact, the flow of federal taxes goes the other way and Red states are net recipients and Blue states net losers.
