John Maxwell book titled "Ethics 101" state that one of our problems dealing with ethics is never a business issue, social issue or political issue, it's a personal issue.  People say they want others to act with integrity but in fact don't act that way themselves toward others. Why is that?

John Maxwell states " The same person who cheats on his taxes or steals office supplies wants honesty and integrity from the corporation whose stock he buys, the politician he votes for, and the client he deals with in his own business."
