Should the public schools develop emotional or patriotic attachment to symbols of the state through the use of songs, literature, and history?

As far as I know, they do. the idea seems to be to inculcate the pupils (once the poor public, now the wealthy 'cos the facilities are good) in the ideas which the state has. former pupils have been given the strong notion to "serve the state" as a sort of "thank you" for their education.
Should they do this, or should they impartially teach ??? dunno.
