Putting too much value on material things makes a person shallow. They think highly of themselves and look down on others who struggle with finances and other things that money is a major factor in. In addition, the rich may be used to solving their problems by throwing large amounts of money around and forgetting the problem entirely and that can lead them to not being able to tell right from wrong any more.
