Goodchild examines the theory of money in a comparable manner to Adam Smith, Karl Marx and Georg Simmel. However by contrast to the conclusions of these thinkers, he proposes that money is essentially created in excess of reserves, making it a simultaneous credit and debt. Since money is a debt that must be repaid with interest in the form of money, then the creation of money imposes a social demand for an increase in profit and an increase in the creation of money in order to repay debt. This vicious circle drives the expansion of the global economy. In summary, Goodchild argues that money is a promise, a supreme value, a transcendent value and an obligation or a law. He argues that money has taken the place of God. It is the dominant global religion in practice, even if no one believes in it in principle.
