South Africa: The unemployment rate among blacks is 28.5%, compared with 5.6% for whites

If those who want work but have given up looking for it are included, the jobless rate is a whopping 41.6% for blacks compared with 7.5% for whites. This is in spite of the fact that at private companies, educated blacks command higher wages than similarly qualified whites: 23% more, according to Adcorp, a big employment agency. Could the higher unemployment rate amongst blacks in South Africa have anything to do with racial differences in intelligence?
