All I can do now is point to the tax bill authors’ own estimates:
“The Senate Republican legislation proposed to eliminate all state and local tax deductions — a move that would produce about $1.5 trillion in additional federal revenue over the next decade to help offset the large corporate tax cut and smaller reductions to individual rates.”

That $1.5 trillion in additional revenue will be paid by people who are no longer able to deduct state income taxes. In other words, they’re paying money to the federal government that it wouldn’t otherwise be receiving.
Well, the Los Angeles Times like all democrats and establishment RINOs claim you have to “pay” for tax cuts and their preferred method for accomplishing that lie is to raise taxes elsewhere to be “revenue neutral.” They’d never dream of cutting spending or cutting government. But I think Trump will be bringing them up to date in the next couple rounds.
