'Progress and Poverty: An Inquiry into the Cause of Industrial Depressions and of Increase of Want with Increase of Wealth: The Remedy' is an 1879 book by social theorist and economist Henry George. It is a treatise on the questions of why poverty accompanies economic and technological progress, and why economies exhibit a tendency toward cyclical boom and bust. George uses history and deductive logic to argue for a radical solution focusing on the capture of economic rent from natural resource and land titles.
