What is it about money that makes people do bad things?
A growing body of psychology research has tried to capture and measure the exact effects of wealth on behavior and morality. That research has shown the rich cheat more on their taxes. They cheat more on their romantic partners. The wealthy and better-educated are more likely to shoplift. They are more likely to cheat at games of chance.
They are often less empathetic. In studies of charitable giving, it is often the lower-income households that donate higher proportions of their income than middle-class and many upper-income folk.
