•While the most famous people from South Africa globally are white or coloured (mixed race), South Africa is a majority black country so in most places you can go weeks & months never seeing any other race other than black people or even any other ethnicity depending on where you are in South Africa. If you're in a Venda area, you're most likely to see just Venda people who speak Venda. It's not because ethnicities in South Africa choose to isolate themselves but most places were tribal areas where indigenous people lived.
• While the wealth is mostly in white hands, black people enjoy relative self-determination. This can be seen by the Royal Bafokeng group & various indigenous language radio stations & TV stations. It's commonly said that 75% of the wealth of the land belongs to whites but black people have managed to scrape together their own institutions such as schools, magazines & sports institutions.
• The biggest market in South Africa is the black middle-class because they have buying power & are larger in population than the often favoured white population. This being said, only one bank in South Africa is "black-owned" & there are very few elite black schools in South Africa so this black middle-class often does rely on white institutions inherited from Apartheid.
• There's a large Asian community in KZN, I've seen a lot of jokes about this but the Indian/Asian population of KZN is said to amount to 7% of the total KZN population & 2% of the total population of South Africa. That means only 7 of 100 people in KZN are of Asian descent & 2 of 100 people of the whole of South Africa are of Asian descent. That's not a lot, just as well, South Africa is not an Asian country nor ever will be or was ever meant to be.
• South Africa is not a united country. I noticed South Africa wasn't united when I studied nation-states around the world. I didn't physically go but noticed mannerisms & how certain lands conduct themselves. This led me to simply conclude that there is no South African people & a South African identity either doesn't exist or is still being fabricated. I don't care what anyone says, I did the research & lived among many diverse groups of South Africa. South Africa is just not a nation-state. Many lands are racially diverse but are nation-states, likewise, many lands only have one race but are divided culturally or by heritage. Mixing of races will not create a nation-state as many hope. Education often plays a role in creating a nation-state & in South Africa, education is still divided according to haves (usually white) & have-nots (usually black). This almost ensures cultural division between races of South Africa.
