I think they are missing this fact. The Rich and "privelaged" want stupid people. So what's the best way to keep those stupid people in line? You have to remove the smarter people and then leave the dumb to do the phsyical labor for you.

The reason why a place like Africa would be allowed to have an increased population is because the truth is, it's a prison. They can easily blockade people from leaving and the sad truth is, turn it back into a slave country with their own little group of test subjects they can use as they see fit.
