Do you hear yourself? You even put quotations over "help" which further proves my point. History has a terrible record of more powerful nations trying to "help" other nations against their own will, and why do you think that this situation would be any different. I'm sure it's so easy to say that as your sitting in your comfortable home drinking tea in your computer chair while other people carry out that task and suffer the consequences. Your support for imperialistic bigotry and supremacist viewpoints towards an entire ethnicity is greatly appreciated. And if I may ask how will this "one child policy" work. Will you fine people for having more than one child, even though they could never afford to pay it? Will you kill all children after the first is born? Will you kill the parent leaving the children orphans? Or will you cut their dicks off and rip their wombs out so they can no longer have children? "Tough methods" to get the situation under control... Cmon get real man. As if that hasn't been said by every white supremacist ever. The best and only logical, non supremacist method is to help them through the transition until they realize it themselves. What will your solution bring besides resentment, hate, and racism between Africa and the rest of the world? Your viewpoint is literally "we'll it doesn't matter, because we're stronger than them"?
Nope, I am trying to save them from nonstop suffering... your viepoints is creating mass starvation and dying of millions if not billions.... you are the bad guy, not me.
And you should check it out how China is doing the one child policy in China, rules are rules and China is doing the right thing, it is working pretty effective there and it can work in subsahara africa too. It is not a human right to have 15 babies if your country is already starving.
China also currently has a large gender imbalance of its young people. This is probably at least in large part due to its One Child Policy.
