Flat above a certain threshold would be fine with me.

The tax plan I favor the most is actually Rand Pauls, where its a flat tax on everything above 50k$ in earnings. People who make under 50k get taxed not at all. Someone who makes 60k gets taxed on 10k, etc

Eliminate all loopholes, and almost all deductions. So its actually a progressive flat tax, someone making a million a year will pay tax on almost all of it. Would free up a lot of overhead costs as well.

For who could be free when every other man's humour might domineer over him? - John Locke (2nd Treatise, sect 57)
