Just get rid of all the obnoxious deductions, exemptions and credits for rich and poor rent-seekers alike and tax at one low, flat rate (say 15 percent until the debt is payed down, then 10 percent or less). You can bet those super-rich, self-indulgent weenies WILL be paying more, if they want to stay on the good side of U.S. law.
Lower the rates, broaden the base.
Yes flat tax is the way to go and it’s Biblical.
