Regarding 2:

This tax law has specifically baked in expirations of some portions. When they come up for renewal the GOP will whine and moan about the unbalanced expenditures and they'll either lapse or be supplemented with additional cuts, the corporate side of these cuts is not subjected to this.

It's fine to say "Oh, things may change down the road" but today they designed a tax cut that will benefit the rich, I do hope we're saved from this ridiculous hand out down the line, but that will be by the actions of other people, these politicians have written the bill as they desire it.
