In Money We Trust? is an illuminating one-hour public television documentary that answers the question, “what is money?” In a narrative that begins in ancient times and takes us to the present day, the film explains how, 2,500 years ago, the invention of money provided a shared measure of value that facilitated trade and cooperation between strangers. Sound, trustworthy money has throughout history fueled great human achievement—from the emergence of philosophy to the high-tech revolution. The program also explores the destructive consequences that ensue when inflation or other forms of instability cause money not to be trusted. In the most extreme instances, such as in Weimar Germany or present-day Venezuela, the economy—and social order—collapses.
