What GOP legislators have been saying in interviews is that (1) the tax code is being simplified, (2) the middle class will get a big tax cut, (3) corporations will get a big tax cut, and (4) corporations will repatriate money stashed abroad.
Well, the more than 500-page bill will not simplify taxes. (No doubt, administrative rulings will expand the number of words needed to explain federal taxes.) The middle class, qua class, gets no tax cut. Some will benefit; others will not. Individual tax provisions go away in a few years, in any case. Corporations will indeed get a big tax cut, and there is a bipartisan consensus that a cut is in order, though maybe not a 40% one. No one really knows what will happen to corporate money abroad. (Firms like Apple don’t need the money in the U.S.; they have plenty on hand that isn’t being used.)
Although Republicans mostly avoid saying it, the party has an unshakable, but empirically unsupportable, faith—“belief” is surely the wrong word—in trickle-down economics. Republicans repeatedly tell us that the tax bill will grow the economy, but they fail to explain by what magical process this is supposed to happen. Never have the benefits of reduced taxes really trickled down to those who most need a break. But, of course, history may come out differently this time.
Apparently, large corporations, newly flushed with money, are supposed to invest in new plant, hire more workers, and slash prices, all leading to economic growth and universal happiness.
