South Africa has a Black Empowerment programme that are basically Affirmative Action on Steroids. Affirmative Action programmes should never run open ended, they should have an expiry date and be regularly reviewed, as in south Africa it has become a tool of discrimination against white South Africans, who are now leaving the country in droves in search of work, the end result is a brain drain for South Africa it can hardly afford.
South Africa's Affirmative action programme have gutted State owned enterprises and caused South Africans the loss of electricity, (there are load shedding). Affirmative Action in addition to corruption have bankrupted local councils who did not maintain sewers with hundreds of thousands of tonnes of raw faeces now flowing into the river systems daily... it is a humanitarian disaster with thousands of children dying from diarrhoea and lung infections related to waterborne diseases. Health and transport services are run down and much of the money to maintain them have been stolen.
I believe the person who placed the ad in the end did indeed agree that the ad was unconstitutional, went beyond the Black Empowerment programme and indeed discriminate against white South Africans.
