The 16th amendment has failed in its purpose of funding government functions. Best it be rescinded. It was a big mistake!
The biggest mistake of the 16th amendment, (besides the fact that it’s application destroys the 4th and 5th amendments), is that the rate was not set in the amendment itself. If they’d set it to 5% and had to go through the amendment process to raise it, we wouldn’t be in the mess we’re in.
