Pacem in Terris §43
Pacem in Terris: On Establishing Universal Peace in Truth, Justice, Charity, and Liberty
43 Thus all over the world men are either the citizens of an independent State, or are shortly to become so; nor is any nation nowadays content to submit to foreign domination. The longstanding inferiority complex of certain classes because of their economic and social status, sex, or position in the State, and the corresponding superiority complex of other classes, is rapidly becoming a thing of the past.
