If it was manufactured in such a way that it wasn't taking from everybody else to pay for lower corporate tax rates (and for pass throughs) then I'd be more inclined to support it. It doesn't make a lot of sense to take all of this away to further diminish discretionary spending around that time of year, to put middle and upper middle america as paying more, while giving these corporations a tax break and a way to manipulate it once again.
We'll see what they do with the tax "loopholes" on the corporate side but my inclination is to think this is going to make it easier for them to bring their effective tax rate down below most of our global peers.
