Why doesn't Germany introduce South African whites, which is better than Middle Eastern refugees?

First of all, you used it wrongly. The introduction is active, and Germany does not want these refugees who are totally incompatible with its own culture if it is not based on political correctness. South African whites have moved out since blacks came to power, and now the rest are mainly white people who have no money and no special skills. They are also worried that life will be more difficult when they leave their homeland. If the German government is willing to give them German citizenship and provide them with basic training for employment in Germany, it is estimated that South African whites will buy a boat ticket to Germany even if they sell iron in a saucepan.
