I do not like the long term liability being added to, here, but, what choice does Trump have? The cost(s) of continued economic damage on the scale we have seen recently, or even only a fraction of that, is (are) and will be far worse. MANY small businesses (and some large ones) are just barely hanging on.
I am having a hard time with the mechanics of the deferred taxes. Gigantic tax payment at end of year? A business or person would still have to budget for the expense. Some people do not have that kind of discipline.
It would have been more fun for him to totally abolish feral withholding, but that is not going to happen.
