Paul Polak is a founder of the nonprofit International Development Enterprises. And he has spent 25 years working to eradicate poverty in Bangladesh, India, Ethiopia, Zimbabwe and other countries in the developing world.
Instead, Polak teaches families and farmers — many of whom live on a dollar a day and own perhaps an acre of land — how to increase crop yields with simple technologies, such as cheap, foot-operated water pumps and inexpensive drip hoses for irrigation. He helped the farmers very well, and it's very useful. After Mr. Polak's teaching, the farmers actually knows how to schedule their own things about money, and so that they can give good academic.
