Oh & sure.. black people can run britain or asian or oriental or whatever... but if they treat the indiginous population as 2nd rate & exploit them.. then they should expect it to come back & bite them.
your confusing the past with the present though - the farm employees were well treated - they are now worse off as they have all lost their jobs due to their employer either being killed or driven out of the country for being white.
simply chucking out all the white farmers when the country relies on agriculture is a pretty silly idea.
The most prosperous nation on that continent is South Africa - a country were the whites stayed in control for a lot longer than any other - now Im certainly not advocating or endorsing apartheid - but I do reckon that making drastic changes such as chucking out the group of people responsible for earning most of the nations income is a pretty silly idea.
Nelson Mandela didnt take any vindictive action when he came to power and white owned farms and businesses were free to carry on operating as before.
Mugabe on the other hand has handed over large farms to his buddies - none of whom know anything about farming nor care much anyway - and the farm workers are now out of work. The farms arent producing anything and a load of the population are starving - but its OK because the few people who own the land now have dark skin.
