The above clause has never been repealed, though people with political agendas founded on an appetite for power and corruption and feudal authority would definitely have you believe the above was repealed by the 16th Amendment to the United States Constitution. The 16th Amendment did not repeal the above, and was never meant to. The 16th Amendment was never intended to impose direct taxation on individual wage-earning citizens. It was intended to impose an excise tax on corporations. The Congress shall have power to lay and collect taxes on incomes , from whatever source derived, without apportionment among the several States, and without regard to any census or enumeration.
Income is profit.
Of course, they carefully fail to tell you and I that when they made those rulings they were referring to corporations who exercise the government-issued privilege of investing in, and thereby earning a profit from, labor. An excise is a tax on the exercise of government-issued privilege. It cannot lawfully be imposed upon a natural right. If the employee doesn't like it, he doesn't have to work there. But when the government collects the tax on labor directly from the employee, or prosecutes the employee for not paying it, government is violating the natural and constitutionally-protected rights of the employee.
