Ending Federal Income Taxes by repealing the 16th Amendment will unleash economic growth. As all Americans will have more money in their pocket they will spend & save it. This will cause rapid economic expansion for those that spend & reduce private debt for those that save & pay off debts with the saved income.
The 16th Amendment is totally unconstitutional as it is the citizens money not the governments to steal. The government can offset the lost revenue with cuts to the out of control government spending.
Finally, as great examples just look at the much more economically prosperous states that do not have state income taxes like, Texas & Florida.
Imagine the growth of all fifty states as all citizens will have more money that isn't eaten up by the Washington D.C. bureaucracy.
