Bernd Senf presents several essays on the deeper economic causes of global misdevelopments. In a generally understandable manner, it is highlighted that the escalating crises are rooted in the problematic determination of individual economic profit, which is the focus of global economic activity. Furthermore, the essays address fundamental issues of the existing monetary and interest rate system, as well as the secrets and consequences of money creation by the banking system. From the analysis of these interconnections, points of departure for necessary changes emerge, should we wish to avoid further escalation of the crises.
