These are the people responsible for the education of the future South African leaders.
That, of course, is the whole problem in a nutshell: parents believe it is the responsibility of the state to educate their kids. As long as that belief persists, we'll raise one generation of ignoramuses after the other.
In my limited experience, I have seen this time and again: parent dump their kids at school and then sit back and wait for their kids to be magically educated by bureaucrats, and simply won't take any responsibility for it themselves. But schools are best an aid, and how well a kid can make use of this aid depends entirely on the education he received from his parents.
Of course, the sad reality is that In South Africa, huge numbers of kids for all practical purposes do not have parents. I have dealt with lots of them. They are screwed, irrespective of what the government does or fails to do.
