David Graeber, an academic and activist who was one of the early leaders of the Occupy Wall Street Movement, has an unorthodox theory that debt was the catalyst for the creation of currency, and Godin found it "mind-blowing."
Godin likes the audio version because he found repeated listens helped him digest the material.
He's not about to join the Occupy movement, he said, but he "found it completely rewired the way [he] thought the world worked."
