If I've got my zeros right ( ) VAT @ 15% represents +-25% of the +-R1,2 trillion, thus equals +-R300 b. So 1% = +- R20 b. So the total of that with the amounts you mentioned = +-R100 b, not the additional R1,2 trillion needed to generate the extra tax to employ the workers in the first place.
So you can see that the numbers just don't add up for govt to be the only employer hiring workers. It's an illogical circular argument. That's all this thread was about. This thread was never meant to be about the economy (the pits), unemployment (awful), corruption (scary bad), SOE's (should be privatised or closed) etc etc etc.
It was just about the claim that the extra +-R0,3 trillion tax over the period was coming because the govt had hired the extra workers. That's almost as stupid as claiming that SA has more Govt employees (+-2.1 million) than the USA (22 million), ie, +-10% of the size. It should be smaller but it certainly isn't bigger!
