Wait just a minute. I'm not sure we have the figures correct. I don't think you are talking about land surface here. It's a silly comparison for a start, since most of this country is semi-desert/mountain.
Besides, a lot of farms are very big - they have to be to be viable.
Let's also deconstruct your argument about white people making up about 20% of population and owning 80% of land.
- Does it make a difference which colour owns the land? We are all Africans (right?). Some would even argue that the farmers are mixed blood anyway.
- The current farmers are experts at farming, that is not in dispute.
- Since farms are quite large by economic necessity, it is quite plausible that they are big, which explains why a few people own large tracts of land. (I hope you aren't proposing some sort of subsistence arrangement??)
- I would also like some land, but I cannot use my colour as an excuse to claim it.
- Black people in the past were never that keen on farming. They raised a few cattle and didn't settle in one place as a rule. One cannot blame land-owners for a communities habits or culture. They are sorry they didn't take up the opportunity, but it's too late.
Just because some oke and his cattle passed a big tree once a year on his way West for 300Km to the grazing pasteur doesn't give him and his ancestors any rights to the city that formed there, does it.
Black people have been proved to come from the North (circa Tanzania). They were known as the Bantu. This is fairly recent history so it is fair to regard them as settlers, just like the white people from Europe.
How do you think the townships were formed in the first place?? These people migrated from rural areas like the Eastern Cape and just squatted. Most did not own anything of note in the cities. Cape Town is a good example of this. It was a long established colony before any Xhosa or Zulu set foot there. Latecomers lost out on the best land deals.
Land that was owned by these people was taken, by an unfair law - yes, but they receieved compensation for it. That is quickly forgotten. They also were allocated land elsewhere. Also forgotten now.
So let's get things into perspective.
