The word ethics refers to many things: a code of rules, a set of principles one lives by, or the study of what is right or wrong.
Why should a corporation be moral?
  1. Because usually it is in its interest.
  2. Because morality is in the interest of the corporate community in general.
  3. Because each individual corporation agreed to behave morally.
  4. Because to renege on its agreement and yet expect others to keep theirs is unfair.
  5. Because to agree to a set of rules to govern behavior and then to violate those rules secretly is inconsistent.
  6. Because to agree to a condition where business and business persons may break the rules if they can get away with it is to undermine the environment necessary for business.
