The social education of young children tries to make them accept the idea that human beings in a Society need to work together for their common good. So the emphasis is on cooperation rather than competition throughout most of this process. This may seem curious, in view of the fact that American society is highly competitive; however, the need for making people sociable in this sense has come to be regarded as one of the functions of education. Most Americans do grow up with competitive ideas, and obviously quite a few as criminals, but it is not fair to say that the educational system fails. It probably does succeed in making most people sociable and ready to help one another both in material ways and through kindness and friendliness.
