I expected behavioural changes in the rigged monopoly game. This is in-line with the results of the Stanford Prison Experiment. Roles affect behaviour. The plus for me was the circular relationship I saw between entitlement and the need to justify achievements.
Paul Piff shows that people with money feel they deserve it. When we have success, we need to justify it; Our mind finds an answer. The answer tells us we deserve our success: “I earned it, I want to hang on to it and I am better than the less successful.”
