Having been there and visited and kept track of South Africa even during the Apartheid era I would say on a timeline our two countries are not that far apart, they just have more third world areas and more third world people. We import the third world massively and then expect magic to turn them into first world people, yeah right. And the Afrikaners are IMO 1st World +, while most White Americans are proletarian in nature.
I understand; I just thought (at least until recently) that we had a much larger tax base (in terms of proportion).
