Frank interviews archeologist Adam Green on his article Killing the Priest- King: Egalitarianism in the Indus Valley Civilization. He explains both his arguments for why the Indus Valley Civilization was (probably) an egalitarian mass urban commercial society that operated in a bottom-up fashion and had really nice houses/sanitation. Also included are tangents on the history of archeological frameworks and categorization, noisy and hidden elites, and questions of information processing and signification.
