  You can't get people out of poverty, you can create opportunities for them to get themselves out of poverty. But what if some never do, for whatever reason? Even if 99% of humans climb out of poverty and stop overpopulating, there must be a few on the end of the bell curve who never will, and that group will multiply exponentially until it eventually dominates the global population. It doesn't matter why. Could be religion, or culture, or genes. But someone is on the end of that fertility curve. It only takes one man breeder and one woman breeder and they will, in a world of non-breeders, soon dominate the world population because of the explosive power of exponential math. So what then? (As an example, Amish in America double their population every 20 years or so. We can calculate that they'll number >250 million within maybe 150 years.)
