A 'tax plan' will be passed.  

It will be the most fantastic fairest plan in the history of the world.  Trump will announce it as such.

It will be the worst and most unfair gift to the richest people in the US ever.  Pelosi and Schumer will announce it as such.

By the 2020 elections, it will be ancient history.  3 years from now?

Your predictions or mine?
