AMEN!!! If the KILL the income tax, a national retail sales tax is fine. But if they only lower it, then they can raise taxes just by jacking up the income tax one year and the sales tax the next. Some of the Lib Rats in Texas tried to sell a state income tax by saying they'd lower the sales and property tax. No way.
That's why HR2525 entirely eliminates the income tax and destroys existing tax records. It wouldn't be easy to start it up again. After the NRST is in place, the 16th Amendment should be repealed, but practically it can't be done beforehand.
