How do I answer my friends in Florida about the tax reform being debated in Congress?

One of the tax reform provisions being debated in Congress is eliminating the tax deduction for State and Local taxes.

I live in a pretty high tax state. For me personally, losing the deduction would hurt a little (to be totally fair, in my personal case it would be offset by the increased personal deduction, also being debated).

Anyway, since I would lose the deduction, I gripe about it.

But I have a couple of buds in Florida (a low tax state) who ask why they should they subsidize states that punish their citizens with high taxes? Why don’t you folks (meaning me) pressure your legislature to lower your taxes, rather than make me (meaning them) pay more to offset your deduction. Washington is going to get their money one way or the other. They will not spend less.
If one state’s people get a big deduction, another state’s people have to make up for it.

I get it.

If I were them, that would sort of piss me off, and I would ask the same question.

So, when I gripe about it, and they ask me the question, how do I answer it without sounding too selfish and whiny?
