We need to have something like a sales tax, so that the IRS loses its power to monitor and terrorize citizens. As a bonus, even illegals would pay.
We don’t need any income or national sales tax.
If the Federal Gov’t would adhere to the Constitution, most of it would not exist, and therefore no “extra” revenue would be required, just as it was from our nation’s start and for many many years.
Return to Constitutional government, and the “revenue” problem solves itself.
