And yet the black population exploded under apartheid as if someone release a nuclear powered cum-cannon. People were streaming over the borders to come and work in a country where you were paid for your manual labor and even a "poor" life here was way better than the usual f***fest that is north, east and west Africa. Many even pursued and attained an education if they really wanted it. It wasn't easy of course, but neither was trekking into the center of a harsh country in the middle of nowhere using ox wagons to build a civilization while at the same time having to die by the thousands to keep the British from doing what they did best.
Here there was no slavery, many of the rural farm workers (which was the majority back then) did in fact have access to clean water, sanitation, immunization etc. as time went on. Even if it wasn't to the same standard as whites had. The vast majority of rural blacks were treated as "part of the family" while implicitly accepting and even propagating a hierarchy that the "white baas" was the patriarch. (and those of you who don't agree with this have no idea what you're talking about).
I also don't know why people think infrastructure just falls out of the sky if you're white. Are we to believe that if the black population started learning from western culture and started building their own pipelines, decent dirt roads (that could be upgraded eventually), sanitation solutions etc. etc. that the Nats will flock in with the Ratels and destroy everything because they're black?
All being said. The "white devils" mostly didn't want to hand over power because they knew it would be a f** up. But power was handed over anyway. And guess what? It's a f*** up...
But sure. Yes, it wasn't a moral system and it was unsustainable given the change in western culture around the world. But let's not kid ourselves into thinking that doing the right thing will ultimately result in the best outcome.
