The aim of this book is to prove that at this present time, with our conditions of production, periodically recurrent depressions, with all their consequences are inevitable. This book will also aim to show a way that such depressions can be avoided, and will suggest a way towards a world production scheme which is fitted to serve the interests of men.

The statistical data to support the arguments made in this book were supplied by Professor Dr. J. Tinbergen, and Mr. D. Groenveld, Eng.
