Uh, in South Africa the majority black masses took over the white minority. What could go wrong?
As bad as things have gotten in South Africa (a coworker is from SA, she and husband became naturalized citizens a few years ago,) it could have been far worse. To see what can really happen, take a look at the example of Rhodesia. It was once known as the "breadbasket of Africa." It's now known as Zimbabwe.
