I like the idea that the people of a whole continent are like those one part of South Africa, or the whole of it ! Why would you suggest it as reasonable proposition? Careful, AOG, your slip's showing ! Do you suggest all the black people in Africa are like it or do you mean the whites and the blacks, Egyptians, and all the rest, Moslems included?
You'll find that when there's wealth and comparative poverty close together there will be robberies,' muggings' and burglaries. That's why Americans often live in gated communities. The Victorians had the same problem. So did people in the C18. There must have been some reason for their carrying small firearms and hanging pickpockets, burglars and robbers, which was presumably meant to be a deterrent..
