Book excerpt: This study reveals how our monetary system reinforces scarcity, and how communities are already using new paradigms to foster sustainable prosperity. In the United States and across Europe, our economies are stuck in an agonizing cycle of repeated financial meltdowns. Yet solutions already exist, not only our recurring fiscal crises but our ongoing social and ecological debacles as well. These changes came about not through increased conventional taxation, enlightened self-interest, or government programs, but by people simply rethinking the concept of money. In Rethinking Money, Bernard Lietaer and Jacqui Dunne explore the origins of our current monetary system—built on bank debt and scarcity—revealing how its limitations give rise to so many serious problems. The authors then present stories of ordinary people and communities using new money, working in cooperation with national currencies, to strengthen local economies, create work, beautify cities, provide education, and more. These real-world examples are just the tip of the iceberg—over four thousand cooperative currencies are already in existence. The book provides remedies for challenges faced by governments, businesses, nonprofits, local communities, and even banks. It demystifies a complex and critically important topic and offers meaningful solutions that will do far more than restore prosperity—it will provide the framework for an era of sustainable abundance.
