Upper class people are more likely to behave selfishly

I have  just read an article in “ The Guardian”  where scientists claim that rich people are  more selfish and mean than poor ones. It was mentioned that privileged people behave consistently worse than others , with a greater tendency to lie, cheat, take things meant for others, cut up other road users, not stop for pedestrians on crossings, and endorse unethical behavior. However, I believe that it is truth in the most of the cases. Of course it depends on a certain personality. Although, upper class people usually think that no one can stop them from doing what they want. They believe that money can buy everything. These people feel more confident because they know that their lawyers will get them out of any trouble without any consequences. What is more privileged people are terribly greedy, the more they have the more they want.To conclude, it would be not very smart to stick the labels to all rich people because there are a lot of different people in the world, but just lets face it, these propositions have  some sort of true.
