The Future of Money: Beyond Greed and Scarcity is a book written by Bernard Lietaer, published by Random House in 2001, and currently out of print.
Lietaer writes that in order to optimally solve problems and create a healthy society, the world needs a variety of currencies in our "toolbox", and that otherwise we are "painting with a screwdriver".
Following the introduction and first chapter, where Lietaer outlines five core problems people are facing worldwide, the book is divided into two parts.
He ends part one with five scenarios speculating what might happen if the five core problems mentioned in the first chapter come to pass, especially after a widespread monetary crash.
In addressing practical issues, Lietaer argues that one important solution is the idea of a complementary clearing house to trade currencies, giving them additional value.
