How does knowledge affect citizenship?

Why do we go to school? Why are we taught good morals and ethics? Out of many possible answers one is to become a better human being. To help ourselves grow better and beneficial for people around us. Knowledge about daily things helps us in many ways e.g. following traffic rules, giving our seats to elders, making people aware of their rights etc. Knowledge about simple morals which we are taught in childhood and continuing to practice them makes us contribute in the improvement of our country as good citizens. For being a good citizen no big deeds or large money donations are required.
