The Richest Man in Babylon

Clason wrote a series of pamphlets for banks and insurance companies in the 1920s, set in ancient Babylon and written in deliberately archaic language, and collected them as this book. The parables teach basic personal finance through characters including Arkad, the chariot builder's son who becomes the richest man in the city.

The substance is a small number of rules. Save at least ten percent of everything you earn before spending any of it. Control expenditure so that necessary expenses do not consume the whole income, and recognise that what people call necessary expenses expand to fill whatever they earn. Put savings to work earning a return rather than holding them idle. Protect capital from loss by investing only where the principal is safe and by taking advice from people competent in the field concerned rather than from those who are not. Own your home. Provide income for the future and for your family. Increase your earning capacity through developing skill.

The book is the origin of the pay yourself first formulation and it has sold continuously for a century. Its use is motivational and for teaching people who have no financial habits at all. It contains nothing about asset allocation, diversification, tax, inflation or compound return mathematics beyond the simplest cases, and the archaic style irritates many readers. The advice to seek counsel from those competent in the matter is sound and is also the sentence most often used to justify following whoever presents themselves as an expert. Treat it as a starter text on savings behaviour rather than an investment book.
