No - a 10% flat tax (no exceptions) with absolutely no deductions for anything except charitable donations. No one should be rewarded or punished for having kids, being over 65, being blind, and so forth. And everyone should pay whether they make $10 or $10,000,000.
That's what you want? Well congratulations. That's what you have. It's called the income tax. How long do you really believe the flat tax will be "flat"?
