A friend who is an anthropology professor (not at Berklee) recommended this 10-part BBC series: Promises, Promises: A History of Debt. I listened to the entire thing and it’s absolutely fascinating! I most enjoyed the first parts, which contained lots of historical information about the evolution of money thousands of year ago. It taught me many things I’d never known before, such as how standardized money came about through the first primative states trying to find a way to standardize recompense to prevent blood feuds. Highly recommended!
