Please note the variance in the sources (even communist party :D ), so not really a biased picture. Everyone knows the grant system is being abused on a massive scale. Also the amount of people on the grant system exploded from 80 000 people receiving grants in 1998 until today's 12 000 000 people. And South Africa is not exactly a rich country...
As for my taxpayer statement, you only pay taxes if you earn above a certain amount. But it is a sliding scale system, so about 2 300 000 people are responsible for 93% of all the collected taxes, supporting 12 000 000 people. Not sustainable.
