Just repealing the 16th amendment would fix a lot of issues.
That is the way to do it, but how are we going to do it? The public is ignorant of how their currency is created and the inevitable default that is in store and that govt granted right to print money out of thin air is damn near priceless - it will not be given up without a fight.
Add the 17th to that as well.
We would be more like the United States again and not the United State.
