Another sampling of proof that humans are stupid. Monkeys and elephants learn from history and pass on the lessons to generations that follow. But humans? Nope! As a species, we are apparently wired to self destruct through governance of our freedoms and possessions. We are forbidden to use talents, bestowed by God, to enrich the lives of the species through our own good will and work ethic. If goodwill and livelihoods are not granted and provided by the government, it is apparently illegitimate.
Much as I detest the hagiography surrounding Mandela, he was the best of the worst in the ANC. If only for pragmatic (economic) and PR reasons, he didn't want to repeat the Mugabe model in South Africa, unlike his sadistic wife Winnie and many others in the ANC who wanted a wholescale slaughter of whites.
It was only a matter of time before things went far downhill: Mbeke, Zuma, and now Ramaphosa who is basically Mugabe-Lite, all people who are unwilling or unable to think practically and learn from history, as you say.
