how is child abuse a social problem?

Domestic violence is a social problem because effects so many more people than just the intended victim. Example lets say a wife is abused, she suffers, pyramid down the children observe mommy crying and daddy always screaming at her, and telling her she is stupid. Pyramid down children become scared, act out pyramid down become a problem for an abusive little person and he begins to abuse them as well pyramid out the mom/wife becomes so stressed and overwhelmed that now her friends, coworkers, parents, siblings are all worried about her, they can see she is being abused, but she is so scared, embarrassed and lost within herself to do anything about it. So yes it is a social problem that all people should be aware of.
