Tim fundamental fact on which the proposal of this book is based is that the purchasing power of the dollar is uncertain and variable, that is, that the price level is unstable. The war has caused the greatest upheaval of prices the world has ever seen. Inseparably connected with this upheaval is grave and world-wide industrial dis content. Because of this and because of the perplexity of business men as to future movement of prices, there has been much discussion going on of the question whether the level of war prices will drop or whether it can be stabilized. To show that permanent stability can be secured is the chief aim of this book; and a specific and de tailed plan for this purpose is presented.
