Uniform identifies individuals with establishment, institution or organization. That is why uniform is prescribed for police, army, railway staff, schools. Even where full uniform is not prescribed, a dress code is prescribed.
so that all children can behave with each other equally. the child of rich family can be a friend and cope up with child of poor family . It is done so that there can never be difference in children.
To show equality the uniform system is maintained and i think even it give identity that this child is school going child. We also have uniform for defense services, medical services etc. may be for identification. :huh: :dry:
