kind of but in south africa there was so little wealth distribution post aparteid you wonder if some forcible redistribution was required (SA has a GINI score of 61 one of the worst on earth
While you are correct that wealth is unevenly distributed right now, it is not such a clear cut problem as white vs black from the old apartheid era.
One of the most important things Mandela was part of was transitioning between the apartheid government to the ANC led government. However, he realized that the ANC and the very poorly educated black population of South Africa didn't know a thing about running a country. He kept many of the Apartheid leaders around in the government to assist in the transition period, and this was essential in the smooth running of the country and preventing another Zimbabwe.
As for the white criminals that got off free, it is once again much more complicated. While the government did oppress the blacks of the country, the ANC that replaced them were not exactly saints either, it could even be argued that they were worse. (Look up necklacing) The way to resolve this issue was the truth and reconciliation commission. Both sides came forth and provided testimony on what they did helping for many of the crimes of that era to come to light. As a result, many people of all sides were granted amnesty.
With regards to current wealth inequality it has more to do with the current government oppressing the poor blacks of South Africa far more than the apartheid government ever could. The government is through legislation trying to court too many groups. They are officially affiliated with the communist party and the unions. These communists and unions are supposedly looking out for the poor workers. However the ANC government and the union bosses love living it up in the luxuries of capitalism. Hence they try to put on a facade of caring for the workers, while sucking up to large capitalist organizations at the same time. This has led to an economic climate that does not really match the economic realities of the country. Which in turn has lead to a massive crunching slowdown of the economy. There is little to no economic growth, and with the abysmal and non existent education system unskilled workers are plentiful, and the skilled workers are pretty much non-existent. As such we have millions of adult people with barely a primary school education expecting high class office jobs, or at least the salary of a skilled job for menial work.
At the same time, rampant self enriching corruption that would make a republican blush, means that government service delivery is at an all time low. This has lead to many government services being mirrored in the private sector which the white middle class pay for to receive. This whole situation has resulted in the white middle class to be able to hold their own and make sure their children are looked after enough for them to eventually receive skilled decent jobs, while the failure of service delivery has robbed the poor blacks of even coming close to those opportunities. The worst part is that the country is rich. the taxes collected are more than enough to really help the poor, and turn things around. Unfortunately that money never gets where it is needed. A simple example is this. on the same day, the government put aside 400 Million for the ANC centennial party, and only 16 Million to train police detectives. Stories like this are very common. Where luxuries for the government officials lie in the hundreds of millions, while services are lucky to get even a million. This corruption is the leading cause of the inequalities of this nation, yes the whites get by and a decent amount of white privilege, and I admit that, but the problems facing the poor of South Africa are far greater than merely wealth distribution.
Lastly, I am glad Mandela is dead.
He has been a brain dead corpse for almost a year since his last severe heart attack. And before then he was a political gimmick dragged out and put on display like a animal in a zoo by the ANC big wigs every election. Being like that in ones later years, death can only be a release.
