Despite the fact I could be on the short end of the stick, Wisconsin still being a "Top Five" or "Top Ten" state for tax burden, the one thing that really has me excited and hopeful. (which, after it goes through the House, Senate, Reconciliation etc. is almost zero "hope") is the proposal to eliminate the state and local taxes deduction.
It essentially provides some back end subsidy for the states who go crazy on taxes, and lessens the pain, and the motivation on those taxpayers to rein in their local politicians and spending. Arguably where personal opinions and input has much more impact.
And I'm sad that cutting the corp. tax rate to 15% would even be controversial. Honestly, it should be slashed down to 10%. That and the current admin's attitudes about agency-level regulations would have the world running back to the U.S. for all sorts of manufacturing in an instant. Not even getting into the fact that any/all "corporate taxes" are all just pass-along costs onto end consumers anyway.
