The ceaseless expansion of economic exploitation, the engine of global capitalism, has come to an end. The futile and myopic effort to resurrect this expansion—a fallacy embraced by most economists—means that we respond to illusion rather than reality. We invest our efforts into bringing back what is gone forever. This strange twilight moment, in which our experts and systems managers squander resources in attempting to re-create an expanding economic system that is moribund, will inevitably lead to systems collapse. The steady depletion of natural resources, especially fossil fuels, along with the accelerated pace of climate change, will combine with crippling levels of personal and national debt to thrust us into a global depression that will dwarf any in the history of capitalism. And very few of us are prepared.
