2019 Reprint of 1963 Edition. Full facsimile of the original edition, not reproduced with Optical Recognition software. This book is an analysis of the causes of the Great Depression of 1929. The author concludes that the Depression was caused not by laissez-faire capitalism, but by government intervention in the economy. The author argues that the Hoover administration violated the tradition of previous American depressions by intervening in an unprecedented way and that the result was a disastrous prolongation of unemployment and depression so that a typical business cycle became a lingering disease.
