What he means is, African culture, some elements of black culture, the third world in general, all of them are constantly trying to co-opt what white western culture builds. He argues that wherever the white population in Africa shrinks or migrates away, the country “becomes a shithole”. So, Africans chase white people.
When white people in Africa relocate to Australia, or Canada, or the US or Europe, the Africans try to follow. Instead of building up their own communities and nations they use and then eventually tear down the infrastructure that whites already built. They never replace it with anything else. Then they immigrate overseas to where the white people are because their own countries are in disarray. Eventually, they start tearing down those countries.
Leftists will call this a “racist” argument rooted in “white supremacy”, but this is a black South African making the point. It’s not racist, it’s just an observation of concrete fact. When Rhodesia became Zimbabwe and the whites were ethnically cleansed, the country collapsed and the black people starved to death.
