Taxing the rich won't work (because there simplyaren'tenoughof them), hence why "the rich" gets constantly redefined to lower and lower wealth levels. Or inflation is used to do the same. Income tax was only supposed to hit the "rich". AMT was only to stop the "rich" from avoiding taxes with deductions. Etc.
Next constitutional amendment:
The 16th Amendment is hereby repealed in its entirety.
No tax, other than retail sales tax and import duties shall be imposed by the federal government, the governments of the several states, or any subdivisions thereof.
Additional language to define tax, retail sales, and import duties so they can't call them fees or call something a retail sale that isn't, or call imports anything crossing state lines, some other garbage you know they'd pull.
