Fairness

A flat tax or the fair tax would treat people equally. A wealthy taxpayer with 1,000 times the taxable income of another taxpayer would pay 1,000 times more in taxes. No longer would the tax code penalize success and discriminate against citizens on the basis of income. Tax burdens would no longer depend on the number of lawyers, lobbyists, and accountants on the payroll.

A flat tax or fair tax would yield major benefits to the nation, including:

Faster Economic Growth.
Instant Wealth Creation 
Simplicity

An End to Micromanaging and Political Favoritism
Increased Civil Liberties
Global Competitiveness
