I actually don't think this is a stupid question. Mandela promised nationalisation of mines, banks and minerals. That belief had formed the core doctrine of the ANC and was enshrined in a document known as The Freedom Charter. I have only been to South Africa once, to most tourist stops and from what I have heard not much has changed. Blacks or coloreds still make up over 85% of the country and are disenfranchised. And anybody thats been to S. Africa can confirm that, but on the same note politics dont move so swiftly and only so much can be achieved. I believe Mandela did the best he could but ultimately had to compromise for the "supposed" greater good, so I give him a pass.
I'd say this post sums it up pretty accurately. And the reason politics moving slow is because self-enrichment is the order of the day for most politicians.
