I saw this in action in Nigeria back in the 90s.
Nigeria passed a law mandating whites make up only 10 percent of all technical jobs. An oil rig, for example, generally had the top 3 jobs as whites, with the rest being black.
Rigs started having some major issues, a couple caught fire.
I was landing in Warri one day in a small Bombardier jet. The flight deck door was open.
As we approached, you could hear the English pilot screaming at the black pilot as we came in to land. We hit so hard my back hurt for a week.
We ended up and the end of the runway with the front wheels in a pile of sand. We walked, with our luggage, back to the terminal.
I remember thinking in my head, “I can’t believe I’m going to die in Warri, Nigeria!”
There was a large chicken farm that was owned by white Bahamians (British heritage). This chicken farm supplied much of the chicken and eggs to the numerous islands in the Bahamas. The government awarded ownership of the chicken farm to some of their black cronies who showed up and took over the farm. Within two weeks all of the chickens were dead. The new owners did not know the chickens had to be fed and watered.
