"Human Dignity" in Buddhism

Can we find a concept of "Dignity" or "Human Dignity" in Buddhism? My understanding is that in the Western World the concept of Human Dignity is used to justify that each of us deserves to be not only treated with respect but also valued as a part of humanity whatever our origin or our place in society. I read that each of us has the nature of Buddha. Could this be considered as the foundation of Human Dignity or a similar notion in Buddhism? What would be the closest(s) equivalent(s) in Buddhism?
