Isn't this situation vastly different than Zimbabwe? I mean, in this case, from the article at least, it sounds like the property was wrongly taken in the first place. Secondly, the current farmers are being paid off decently. I don't recall Mugabe doing that...
I don't know the circumstances of how property was transfered generations ago. What i do know is that somebody whose great grandfather was a subsistence farmer decades ago has in all probability lost all knowledge of how to manage land under cultivation. Especially large scale cultivation. So, a wholesale transfer from the knowledgeable to the ignorant is no different from what took place in Zimbabwe. There will be joyous festivities as cattle are slaughtered and eaten along with the seed crop. The following season, there will be famine.

There is a 354 year history of white farming in South Africa.
