Thorstein Veblen was probably the greatest economist working in early 20th century America. In this treatise, Veblen sets out the preconceptions and uninformed ideas people have when beginning to study the economy, taking each problem and addressing it in turn, hoping to open the readers mind to a better understanding of one of the most difficult and complex problems of the modern world, the economy. We are republishing this work with a brand new short introductory biography of the author.
