From to time to time, Laissez Faire Books reissues a book written by an enemy of economic freedom: this ebook is one of them. Its author, John Maynard Keynes (1883–1946), is famous for his macroeconomic theory that, from the 1930s on, ushered in a new era of government intervention. In this short book, Keynes explains the political philosophy underlying his economics. One cannot criticize Keynes without reading him. With a new foreword by Pierre Lemieux.
