This week, we’re joined by Robert FitzPatrick, founder of Pyramid Scheme Alert, and co-author of False Profits: Seeking Financial and Spiritual Deliverance in Multi-Level Marketing and Pyramid Schemes. He’ll discuss the promises and pitfalls of schemes, and how to tell legitimate direct selling from multi-level marketing scams. And we speak to Paul Piff, researcher at the Institute of Personality and Social Research at the University of California, Berkeley, about his research on the relationship between social class and unethical behavior.
