I certainly hope those proposals get somewhere.
There is a plan that eliminates ALL taxes on ANY income, deufnds the IRS, destroys existing income tax records, and erases the entire income tax code. It's HR 2525. Do a thomas-loc search and read it. It's not too long at all. You can find synopses around...I'll direct you to a few should you ask.
The same plan has HJR 45 - an amendment to repeal the 16th AND make the taxation of any kind of income unconstitutional.
