In the story’s world, everyone would have a life score. People would get positive points for good actions and awards (i.e. perfect attendance award) and negative points for bad actions. The scores would be displayed on badges worn at all times. The scores could be given by a computer system or the government. Instead of a class system based on birth or wealth, it would be based on one’s score. People with high scores get perks and more authority. The plot could be based on someone finding out about corruption in the point giving system in the government or hacks of the computer.
A religion could be based on the system. You get into heaven if you have a minimum score and hell if you have a low or negative score. There could also be a purgatory for low scores. There would also be tiers in heaven and hell.
The scores would probably have to be normalized for age so an older person doesn’t automatically have a higher score. It wouldn’t be proportional since age should count for something.
Maybe points can be converted into money or yearly tax deduction.
The government could be harsh and kill anyone whose score goes below a certain level (i.e. -50). You would probably get a warning in the mail saying, “Warning: Your score has fallen below acceptable limits! Please do good deeds to raise your score.” Of course this means that you can murder someone and get away with it as long as you do enough good deeds.
