South Africa, the country, has a population of around 50 million blacks. Africa the continent has many, many millions of spare blacks.

"Segregation barriers"? Or do you mean the entrances to gated communities - that were created to stop bad guys from murdering residents? Things that have only sprung up due to the authorities' inability to fight one of the highest crime rates on the planet. If these were 'segregation barriers', then why is the black government doing this?

You say there's a huge gap between rich and poor - Rich and poor is NOT "blacks" and "whites", The South African government currently robbing the country to enrich themselves.....White, are they? There are more wealthy blacks than there are whites.

How about the police and military?

South Africa USED to be the richest nation in Africa. That status is declining quite sharply as it turns into another Zimbabwe. The national electricity supplier (Eskom, run by 'the blacks' since 1994) can't keep the lights on - it's worse than californie - they've had roilling blackouts for almost 20 years now)

Who are 'the elites' in South Africa? What is their ethnicity?

These 'blacks' of which your wife and her friend speaks - were they South African blacks or one of the millions of illegal immigrants who brave river crossings with crocodiles and hippos just to get some of that sweet, sweet oppression.

And if 'the blacks' are unhappy - with a black president and government since 1994 - what do white folk have to do with that?
