Black South Africans have failed to maintain the economy that even the oppressed Blacks and colored of old Apatheid South Africa thrived under.
It's an old pattern. They tried socialism. When it failed, they tried socialism with even harsher controls. Now, that has failed, so they scapegoat a minority and take their property too temporarily keep going.
Once they have stolen everything from the whites, they will turn on successful blacks and colored.
That said, I would just as soon those oppressed White South Africans go to europe rather than to the united states. I don't want to pay for their security against attacks by deranged Democrats.
