You can't blame him for being a noob! He is not a politician to put it in a nice way for the masses, with a pretty name attached to it... like "The Salvation of Africa Project" (that would be intended to stop them from coming to Yurope!)
But I think there is cheaper labor in Africa than in India or some other Asian 3rd world country. So... business people should think about that. But I think they would probably need some military enforcement to do business in those places first. And after wealth and prosperity comes, then the population growth will stop.
