I know it sounds sort of crude but it is true.. If you want to erradicate poverty from the world,  get rid of the poor first.. No no I am not saying kill them but as Mercia said, give them birth control.. Force them with birth control injection or bribe them saying that all women who come and get their tubes closed will get a reward of so and so amount of money.. I am sure women will just come for the money and then voila, no more poor kids.. Poverty gone from the face of the world..
