Africa's population was brought up because many dystopian novels/stories have an upper class (like 0.01%) who's rights are incredibly restricted but rewarded with resources/privileges where as the vast majority of the population can mostly do whatever they like but are given nothing. 1984 is a great example... there are many more examples. ie poverty and/or living off the grid = freedom. I guess when I read dystopian like things where this is the case I'm always begging the question... why don't the characters just move out of the restricted society (in some cases the story answers that but in many its not).
