"In the first of two studies, researchers found that those who drove more expensive cars (an admittedly questionable indicator of economic worth) were more likely to cut off other cars and pedestrians at a busy San Francisco four-way intersection than those who drove older, less-expensive vehicles."

"According to this book, the average millionaire drives a Ford F-150 pickup truck. 80% made their money in one generation, and only 20% had more than 10% of their income come from inheritances. The average millionaire does not drive the latest-year's car, nor does he or she wear expensive clothes. The average millionaire invests around 20% of his or her income annually."
"In other experiments, wealthier study participants were more likely to admit they would behave unethically in a variety of situations and lie during negotiations."
So, couldn't this be interpreted as wealthier study participants were more willing to be honest about how they would act in a variety of situations?
"In another, researchers found wealthier people were more likely to cheat in an online game to win a $50 prize."
It would be interesting to know how they defined "cheating" ...
I wouldn't be surprised if it was that wealthier people were willing to use their back-button to correct errors and then re-submit a form, and while this may not be the most honest way to win a prize if it was not explicitly stated that this was against the rules I could see how someone would not see it as being unetical to do this.
