Why We're Still Happy
"Indeed, humans are remarkably attuned to relative position and status. As the economists David Hemenway and Sara Solnick demonstrated in a study at Harvard, many people would prefer to receive an annual salary of $50,000 when others are making $25,000 than to earn $100,000 a year when others are making $200,000. Similarly, Daniel Zizzo and Andrew Oswald, economists in Britain, conducted a study that showed that people would give up money if doing so would cause someone else to give up a slightly larger sum. That is, we will make ourselves poorer in order to make someone else poorer, too. Findings like these reveal an all-too-human truth. We care more about social comparison, status and rank than about the absolute value of our bank accounts or reputations."
