Distributive justice is defined as how goods or wealth are portioned based on a common and accepted standard. But what is an ideal standard? For Feinberg, there are six principles to which distributive justice may be based on: Perfect Equality, Need, Merit by Skill, Merit by Virtue, Achievement, and Effort.
In Perfect Equality, goods are evenly distributed among the members of the group. This is because individual differences do not influence how much a good is acquired.
