Increased Civil Liberties

Under current law, people charged with murder are presumed innocent and thus have more rights than taxpayers dealing with the Internal Revenue Service. By contrast, a flat tax would eliminate almost all sources of conflict between taxpayers and the government. Moreover, infringements on freedom and privacy would fall dramatically since the government would no longer need to know the intimate details of each taxpayer's financial assets.

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

Faster Economic Growth.
Instant Wealth Creation 
Simplicity.
Fairness
An End to Micromanaging and Political Favoritism

Global Competitiveness
