The excellent blog PsyBlog discusses a recent study that attempted to determine whether upper or lower class folks tend to cheat the most. From the post:
The results were pretty clear. Overall about a third of drivers failed to stop for pedestrians, but it was those in the most expensive cars that were disproportionately represented amongst the discourteous drivers. About 30% of drivers in the cheapest cars failed to stop compared with over 45% of those in the most expensive cars.
Piff and colleagues then retired to the laboratory to see if they could catch upper class people cheating more than the lower classes on other sorts of tests. Sure enough, they could:
"...upper-class individuals were more likely to exhibit unethical decision-making tendencies (study 3), take valued goods from others (study 4), lie in a negotiation (study 5), cheat to increase their chances of winning a prize (study 6), and endorse unethical behavior at work (study 7) than were lower-class individuals."
