Your comment mentions its own fatal flaw: "becoming western style consumers". From what we've seen in the last hundred years, that's strongly positively correlated with (and probably causes) decreasing birthrates. The only other broadly successful way to decrease birthrates was to make it the law, and the one country that did that has abandoned it because of the negative economic effects of too-low birthrates.
