Okay, an actual serious post about the state of South Africa ITTL. First off, South Africa also includes Namibia, Lesotho, eSwatini, and Botswana, and is basically the economic engine that drives Africa. Thanks to a much more gradual decolonisation and borders that sort of make sense, Africa as a whole is better off than OTL, with European nations making sure that their former colonies had what they need before they left entirely.
That’s not to say everything is wonderful in Africa. Boko Haram is still active and has recently staged a coup in several Lake Chad region countries (hence the UN peacekeepers) and there is still severe poverty in some regions thanks to corrupt politicians and governments, things are on a generally more even keel, with the standards of living and GDP per capita in South Africa being more or less on par with OTL Portugal.
