Does the Bible affirm class and/or social hierarchies?

Genesis gives a kind of pecking order of creation Mankind over the animals, Man over woman, God over all. I was wondering if the Bible also gave scriptural authority to some men over other men, whether they be church elders over congregation, kings and noblemen over their subjects, the wealthy over the poorer, the saved over the sinners, the Hebrews over their pagan neighbors etc.
