May of the arguments they present don't stand up to common sense let alone any sort of intensive analysis - like "the government taxing itself" conundrum since that's already being done.Your ignorance on taxes is astounding.
Just as you are wrong about taxpayers are the tax base, you're also wrong about the withholding of employee's wages to the advantage of the employer (government) is at the same time taxing the employer (government).
Guess you didn't read the economic explanation - or understand it!
That's all your post shows.
