More accepting of greed
The other experiments were conducted in a laboratory. Some were done with UC Berkeley undergraduate volunteers, while others involved U.S. adults who were recruited through Craigslist or Amazon’s MTurk website and who participated online. In all, more than 1,000 individuals took part in the experiments. A variety of ethnic and racial groups were represented, although most participants identified themselves as white (European American).
These experiments consistently found that people who considered themselves upper class (as determined by a standardized questionnaire) were more likely than lower-class participants to make unethical choices, such as taking items intended for others (candy earmarked for children!), lying in a job negotiation, and cheating to increase their chances of winning a prize.
In one experiment, for example, participants played an online dice game in which they were told that the highest score from five dice rolls would receive a cash prize. They were also instructed to report their own scores. What they didn't know was that the game was rigged, and no player could score more than 12 points. Upper-class participants were more likely to report that they had scored more than 12 points — in other words, they were more likely to cheat.
