Full Idea
The first main argument for utilitarianism is that people matter equally, and hence each person's interests should be given equal weight, and hence morally right acts will maximise utility.
Gist of Idea

A Reaction
The point is that this starts from the aim of equality, and infers maximum utility as its consequence. Equality has a primitive value. Whenever you dig down to a primitive value in a theory, I just find myself puzzled. What can justify basic equality?
