No, it won't necessarily run up the deficit. You can still have a deficit neutral tax reform plan without the 15% corporate tax. Like I said, the 15% is just Trump's baseline, it doesn't make or break the potential for a worthwhile tax reform plan.
Of course it will run up the deficit. If you don't bring the good jobs and industries home, you're cutting revenue with personal income tax cuts with no offsets from other sources like new good jobs and industries with the 15% business and corporate tax cut, then it's a mathematical certainty that you'll run up the deficit. I don't care about running up the deficit for 1 to 3 years if the business and corporate tax rates are low enough to bring our industries and good jobs back home because those businesses and new payrolls will more than pay for the lost revenue as well as reduce the poverty spending in volumes, but "reform" without the business and corporate tax cuts is just silly.
Assuming a 15% corporate tax rate is the only way to create a deficit neutral tax reform plan is just silly. There are all kinds of spending cuts, adjustments, and shifts that can be done to achieve such a goal.
If you're placing all your eggs in one basket and basing success on a 15% corporate tax rate, you're going to end up being disappointed. Mark my words on this, you'll not see better than 20% to 25% ........ that's if we can even get a plan through the U.S. Senate.
I'm not talking about a "reform" plan. I'm talking about a 15% business and corporate tax rate to bring our jobs and industries back home.
Nothing anyone does to the income tax besides repeal it is "reform", it's just Same O Same O for the past 113 years.
