[Principled]

No need to have a decades long debate, the text of the 16th is quite clear that it grants power to collect an income tax. If this power existed previously, then why the 16th?

Because of the way they want it collected.

This is secondary though. The amendment in question does indeed repeal the 16th - and it goes further to make unconstitutional the taxation of any type of income.

You mean the 'proposed' amendment.
