Egalitarianism

Egalitarianism (from French égal, meaning "equal")—or, rarely, equalitarianism or equalism—is a trend of thought that favors equality for all people. Egalitarian doctrines maintain that all humans are equal in fundamental worth or social status, according to the Stanford Encyclopedia of Philosophy.

Not to be confused with Feminism which is attempting to get equality solely for women.
