Again, subsidiarity. Without that you simply can’t understand what Pope Benedict is saying. And you don’t.

Socialization also presents dangers. Excessive intervention by the state can threaten personal freedom and initiative. The teaching of the Church has elaborated the principle of subsidiarity, according to which "a community of a higher order should not interfere in the internal life of a community of a lower order, depriving the latter of its functions, but rather should support it in case of need and help to co- ordinate its activity with the activities of the rest of society, always with a view to the common good."7
1885 The principle of subsidiarity is opposed to all forms of collectivism. It sets limits for state intervention. It aims at harmonizing the relationships between individuals and societies. It tends toward the establishment of true international order
1894 In accordance with the principle of subsidiarity, neither the state nor any larger society should substitute itself for the initiative and responsibility of individuals and intermediary bodies.
From what I have seen, I think that the principle of subsidiarity is an excellent concept. I must add, that I believe that a "World Authority" will honor this principle only in the breach.
