To stop poverty, we must stop corruption first. All those countries who have highest rate of poverty have highest rate of corruption. See for instance, India, Somalia, Myanmar they have common enemy aka corruption.
Issues such as corruption, ethnic and religious violence, illiteracy.etc stems from the same root cause. Until we tackle the root cause, poverty will exist in this world. I am talking about overpopulation. The planet is currently supporting 7.5 billion humans, although it has the capability to support only a fraction of that many people. There are not enough natural resources to keep everyone wealthy and therefore poverty is increasing. The largest reduction in poverty has been noticed in countries such as China, where strict population planning policies were implemented.
