Well, currently I believe the problem in the governance of South Africa comes from the fact that the following have occurred.
1) Members of Parliament and National Council of Provinces are not directly elected by the citizens. The party picks its reps and you vote for the party. This means that there is little accountability to individual members.
2) One party controls majority of the vote. It has no need to placate other parties who directly contest elections. (It merely has to keep its own members happy)
3) Government agencies and civil service have been "transformed". A large portion of the direction of these agencies are high up members of the majority party. Not professional civil servants but professional politicians. Their retention and advancement depends on their position within the party, hence if they anger the party, they are out. This creates a position where party loyalty overrides all other concerns.
4) Isolation of leadership. The people on the top positions of these organizations have completely lost touch with the lower echelons. Amongst the things that this results in is that when additional funds are allocated for salaries it is eaten up at the top of the organization. For example in one takes the top five police officials and combine their yearly salaries and benefits packages you will see that you could have an additional 70 police officers. Is Jackie Selebi and his deputy directors more useful than 70 police officers? Not to my mind. Of course the directors do need to be paid more, but to such a level that 5 at the top are paid more than 70 of the people who actually do the work. Of course this is even worse in the public sector.
Or consider the municipal managers who are unqualified yet earn more than the president. Why are they in place, and why are they untouchable. Patronage and lack of accountability.
The key, indeed only criteria that should be looked at when appointing those who act in the public interest should be competence and knowledge. Of course we are not the only country suffering from this, the United States is particularly beset by this affliction, (see the appointment of a horse show judge to head the disaster management organization)
South Africa is not so poor that it cannot afford to maintain itself. South Africa has the 28th largest economy in the world and is only the 26th most populous country whilst it is the 25th largest (land surface) in the world.
So what is the problem. Incompetence. The majority of the countries departments cannot make it through a financial audit. E.g. money is being stolen from the public on a vast scale.
Consider this: Is Manto the best possible person in the country to be the health minister? Is Ivy the best person to be telecommunications minister? If not, why they ministers? If they are the best our country can do, then we are all in deep trouble, for if we cannot do better than either of these it is saddening and utterly depressing.
