Human nature is universal, people are individual.
Self interest is a matter of human nature. In every society no matter how it is organized people will generally seek their own interests over everyone else. This is one of the generalities of human nature.
People are individual (this is also a generality of human nature) in that everyone will express some form of individuality even in the most conformist culture. Also even though everyone can be expected to seek his own interest it is never wise to expect that any one person will seek his own interest even when it may seem that he has an obvious interest.
