"Banker to the Poor: Micro-Lending and the Battle Against World Poverty" by Muhammad Yunus chronicles the development and impact of microfinance as a tool for combating poverty. The book details Yunus's journey in establishing the Grameen Bank, which provides small loans to impoverished individuals, particularly women, to empower them to start their own businesses. Through personal stories and empirical evidence, Yunus illustrates how micro-lending can foster economic self-sufficiency and improve living conditions.
