I’d suggest using this formerly racist concept known as “Math”.
The wild spending of the high tax states is masked to a large extent for the wealthy by the deduction.
I note that there have been others that have tried to explain this alien concept to you.
I just told you “math.” High tax states contribute more in taxes than do many low tax states. That is a fact. You tried to introduce the notion that high tax states are being “subsidized” by everyone else, which is completely in accurate. Furthermore, eliminating those deductions will not just affect the “wealthy”, but millions of middle class families. Rep Peter King (R-NY) floated an income cap where middle class families would retain the cut. Guess what? Paul Ryan rejected it, because the chance would not generate the $1.5 Trillion they need to offset slashing the corporate rate. In other words, they need to soak the middle class and want that money.
