Let's say you have a really insecure boss and you are very smart. Once you start questioning him consider yourself out very soon, work keeps piling on as punishment, until you leave for better.

Same with ANC they cannot lead smart ppl, else they will question and leave. They must keep them uneducated and keep feeding them lies of a "common enemy", previously apartheid, now the white "privileged" man. 

The uneducated will clap their hands & shout ANC even if not happy & you tell them to do it.😏😏
