Herman Cain is proposing an overhaul of the American tax system that he calls the 999 Plan. If this sounds like a pizza promotional, well, what do you expect from the former CEO of Godfather's Pizza? Please hold the jokes about the whether the plan comes with extra toppings, garlic bread, and a large drink. However, other people are a little more concerned about the potentially sinister numerical significance. 999 is considered by many to be a variant of 666, which has traditionally been called the "mark of the beast", at least according to conventional biblical translations of Revelation 13:18, which say, "Let him that hath understanding count the number of the beast: for it is the number of a man; and his number [is] Six hundred threescore [and] six". This is supposedly the number or seal used by the Antichrist to mark himself and all those who cooperate with him.
Interestingly, verse one of Revelation 13 also may apply to Cain, because it says, in part, "upon his head is the name of blasphemy". Well, Cain, as you will recall was the murderous brother of Abel, and the biblical Cain was given the Mark of Cain, as per Genesis 4:15. The name Cain might therefore be considered blasphemous in itself, since it is the name of the first murderer who rebelled against Yahweh.
Of course, Herman Cain says it's just his flat tax rate proposal where each individual would pay 9% income tax, corporations would pay 9%, and there would be a 9% sales tax. As the link above notes, this would absolutely wallop the poor, because he wants to make it so that everyone has to pay it and many poor people end up paying no income tax after deductions. Furthermore, this 9% federal sales tax would be on top of the sales taxes charged by many states. In fact there are also some cities that charge sales tax. So people could end up being charged state, federal, and municipal sales tax on a purchase. Naturally, wage earners on the bottom rungs would take the largest hit from this because they usually spend all of their incomes on necessities like food, gas, etc.
So even if Cain's 999 plan is not a satanic conspiracy, making Herman Cain the Antichrist, it would be extremely bad for anyone but the richest of the rich. Cain has made it very clear, from day 1 that the super-rich are the only people he cares about. That's why his 999 plan shields all investor income. Jesus spoke of helping the poor. Cain is the antithesis of Jesus in that he only cares about helping the rich.
Note: I am NOT saying that I take Revelation 13:18 seriously, or that I believe that it is an authentic prophecy. Many serious students of Christian theology have concluded that the 666 reference, which is alternately 616 in some of the oldest translations, was a likely reference to the Roman emperor Nero, who was well known for his persecution of the early Christian church. Nero, if the tales of his actions were true, would fit the bill as an "Antichrist", in the sense of being anti-Christian, far better than many of the people who have been labeled possible antichrists over the intervening centuries and millennia since this prophecy has gone unfulfilled.
In modern times, people have come up with all kinds of fanciful conspiracy theories, claim that 666 shows up in barcodes, or that these digits will be embedded in chips which are implanted inside of people as an alternative to money.
