Most countries are built on myths, almost unanimously accepted as culturally and socially binding. Symbols, apart from myths, play an important role in shaping the perception one has in relation to authority, at least on a theoretical level. In practice not many people pay attention to the symbols around them and the degree in which we process them on the unconscious level can be debated. Symbols are codes and in order to decode these you need the key and depending on your own development and cultural background you may unlock different meanings although rarely contradictory.
