Can money really make a person mean? In this second and final programme, Jack heads to Hong Kong to explore whether our preoccupation with money is affecting the way we treat other people.

Jack hears about the growing body of evidence indicating that we behave with less empathy, kindness and generosity when exposed to the idea of money. Most of the research so far is from the United States, but Jack stages his own psychology experiment at the City University of Hong Kong to explore how far these findings hold true there. He hears from leading expert Kathleen Vohs and from two Hong Kong academics who have started asking whether money even affects aggression and attitudes to casual sex.
