There isn’t a black nation of the face of the earth fit for human life.
Got that right.
This is utterly untrue.
For example, Botswana: at the end of colonialism one of the poorest British districts one completely landlocked and which only seems to have existed as it was because of a railroad and that the South Africans had withdrawn from the commonwealth, became one of these new nations; however, unlike the socialist loons taking their cues from the French and Russian revolutions who proceeded to drag much of Africa down this place was blessed by a leader said by some to honor the American, and George Washington in particular.
IIRC, the story goes that his nation was held in such low regard by their former colonial masters that at one point a Brit was to have unknowingly joked in the presence of this man that he must live in a tick hill. To give you a further idea of the character of this first president of his country he was to have proceeded to call his residence just that.
During Khama’s time and since a nation with little going for it (only a tiny number of educated people, for example) initially has steadily advanced will it is considered a middle income nation where education and enterprise are valued.
It is not the color of their skin that has failed many black people ... it is the color of their politics.
The UN has what they call the Human Development Index. It is their version - somewhat warped - of a Standard of Living index.
Under this index, the highest ranking black run country is The Bahamas, at 55th.
I can only imagine that this is as high as it is because of tourism.
I have been to the Bahamas many times. Outside of the tourist areas it is a cesspool.
