A soldier enlists in order to protect his or her nation, family, and friends.
A citizen becomes a police officer in order to protect society from crime.
A citizen becomes involved in politics hoping to create a change in society.
An individual works with a non-profit with the intent of helping society.
A graduate becomes a social worker so that they can shape a better society.
These are the reasons that the benevolent tool gives when asked why they do what they do. They believe that they are doing good by choosing a public service career. Fighting crime, passing progressive legislation, killing terrorists, and providing help to those who need it bolsters their belief that they are creating change, that they are creating a better society. What no one ever discusses, and I presume most people never see, is the role they play in maintaining the status quo.
