This is not what i want.
What i want is get more places with South African look, independently if its Econmy Get Even Worst or Its Get better.
I dont Want Africa Asia too look Like the USA or Australia
That's just South Africa's issues. And looking at Apartheid South Africa compared to, say, Brazil, South Africa definitely did worse overall. If you want a nation able to implement an Apartheid sort of policy, that's kinda hard considering how so much of Asia ended up as a graveyard for Europeans who traveled there.
And Africa is really the best place to make a large amount of whites. Asian states seem far more organised compared to African states, in terms of those in areas Europeans are most able to colonise and settle. Look at a climatic map and relate it to various empires and organised nations.
The "South African look" in many TLs is probably likely to end up mixed-race whites and Africans, like the Cape Coloureds. As I said, all of southern Africa south of the Zambezi is good land for Europeans (Portugal, say, could've gained it OTL), but more than likely, you'll end up with a bunch of Cape Coloured-looking people more than anything else. But sure, they could be economically like Brazil, without a doubt, though certainly with the same regional disparities as Brazil (the further south you get, the better off, the north is the poorest).
