Seven scientific studies have shown that people from higher economic classes behave more unethically than people from lower economic classes. Specifically, the studies showed that rich people were more likely to lie in a negotiation, cheat to win a prize, and endorse unethical behavior at work.
Two of the studies showed results that cause me to shake my head and roll my eyes. The first showed that upper class people were more likely to break the law while driving. Specifically, they were significantly more likely to cut off pedestrians and other drivers. (This should not surprise most drivers!). The second, showed that rich people were more likely to take candy that had been set aside for children. (In other words, rich people literally are more likely to take candy from babies!!!).
Clearly the 1% and their Republican allies are the problem.
