Disgraced South African politicians cannot resign

In many countries in the world a politician will be forced to resign, or resign voluntarily due to poor performance or mistakes. In South Africa, this is not the case. Over the last few months we have had a few stark examples of South African politicians who have failed dismally in their provision of services and their ability to act professionally and show a decent level of management. I can think of two examples (among a list of very many). The first is the Basic Education Minister Angie Motshekga. Consistently the Education department fails in a myriad of areas including: textbook delivery, teacher performance, abuse of children in schools and teacher absenteeism. Despite all these and many others the minister refuses to resign. Why? The second is Police Commissioner Riah Phiyega. Following the scandal that was the death of protesting miners at Marikana , having been shot by the police, Riah Phiyega has been disgraceful in her response. It is so obvious that she has absolutely no idea of how to run the police, no idea of the structures and procedures required, and no desire to take responsibility for the worst police brutality since apartheid. Despite this, she refuses to resign. Why? My opinion is that in other nations politicians get their positions based on expertise, experience, and desire to serve. In South Africa, politicians get their positions based on party loyalty, regardless of ability. If a minister in another country resigns they still have their skills and experience, which will allow them to get another job. In South Africa, if ministers are not in government they will more than likely not be employable anywhere else. If they resign, they join the rank and file of the rest of the unemployed in our country, as so quite simply, they cannot resign. It is a matter of urgency that the government begin employing people with the necessary skills required or we will continue to slide into mediocrity.
