"The USA" as Cosmos?

It seems to me there is a tendency -- amidst the general sleep of, as I see them, most of American minds -- to not recognize that the USA itself, viewed as a whole social-political entity, is less than life and world, thus they tend to reason, moralize, dream, idealize...as if America(n) was a sufficient world. Life and world are more than the USA. Obvious? Most do not seem to reason so.
