Couldn't help but notice that even the "Griqua" community in South Africa live better off than "Al-Akhdām"(Afro-Yemenis) in Yemen who are still slaves.

FYI, the Griqua are not Coloureds and are not Khoisan. The Griqua consider themselves as being South Africa's first multiracial nation with people descended directly from Dutch settlers in the Cape. And like the Boers they migrated inland from the Cape and in the 19th century established several states in what is now South Africa and Namibia.
