Debt: The First 5,000 Years
Dr. David Graeber is a brilliant anarchist anthropologist so it is fascinating to listen to him discuss humankind's past and current concepts around debt. Jim Rogers is prone to use the phrase "throughout history", however Graeber takes that approach to a much higher level and he discusses some pretty interesting examples.
While many people are looking to economists to solve current financial crises around the globe, the solution(s) are far more likely to be based on human needs and emotions. Does the majority of the population serve a global banking system or should it be the other way around? I would suggest that the study of psychology and anthropology points to a more radical solution than most people currently envision.
