Community for Children
Community is the presence of shared values, common goals, a sense of history, and attachment to, even affection for, a common place.  Children who experience community are more likely to become community builders themselves.  Children internalize the values, goals, and affections that they gain from living in a community through practices established by its members. 

Trust is an essential building block of community.  Childhood is a critically important time to learn to trust.    A caring and stable family is one of the most indispensable institutions in a community for building trust.   A child's capacity to trust can be shattered by broken promises, failed vows, the disappearance of a parent, and the failure of a family, locality, or society to provide basic survival goods.  Therefore, homelessness can destroy a child's trust in others.  So can routine hunger.  So can unchecked neighborhood violence or child abuse.
"Making a child is a moral act.  Obviously, it obligates the parents to the child.  But it also obligates the parents to the community."

Amitai Etzioni, The Spirit of Community, p.54
