It's not our fault in the West that Africa can't control its population numbers.  Their overpopulation problem is theirs to solve.  The West has spent billions and billions of dollars over the years in foreign aid and nothing ever changes; the population numbers just go up and up.  
The Third world is already pouring into western countries and that costs us a bundle.  No matter what we do, it's never enough.   I'd say that a lot of us have donor fatigue, plus guilt fatigue for all the harping on us that globalists do.  I'm all for giving Africa birth control, but no western country is obligated to do so.
