Forget that we have a new finance minister, David van Rooyen. Instead, be worried about what lies ahead as our economy continues to bleed. We should again be asking whether President Jacob Zuma is the right man for the job.Is he capable of turning around an economy that is on its knees?Twenty-four hours after he shocked the nation by firing Finance Minister Nhlanhla Nene, Zuma has still not given us concrete reasons as to why Nene had to bite the dust.Zuma has the constitutional right to hire and fire anyone in his cabinet. But it is important to remember that he is running this republic on our mandate as voters.Two of South Africa's most important cabinet portfolios - minerals and finance - have new ministers at the helm, plucked from junior government ranks.Our economic outlook is frankly depressing - but the answer waved in our faces is a Band-Aid from China.It does not help that Zuma and those close to him keep changing the drivers when we all know that it is the vehicle that is at fault.The ruling party and its alliance partners seem to be in the dark as well and offer no solutions to our rapidly worsening economic woes.We have to ask why Nene was axed. If it has to do with Zuma's political ambitions and was aimed at safeguarding his close friends, we have a duty to challenge him .South Africans cannot continue on this path, the punch-drunk victims of a dying economy.That is why it is important that Zuma brief the nation and convince us that he made the correct decision in axing Nene.Failure to do so will add to the conviction that all Van Rooyen has to do in his new job is sign off on various deals favoured by our leaders but which Nene red-flagged.As the storm gathers, economists tell us the worst is yet to come - and South Africa should brace itself...
