What is the common law principal that allows the state to assume a parental role and to take custody of a child when he or she becomes delinquent, is abandoned, or is in need of care that the natural parents are unable or unwilling to provide?

Parens Patriae

Explanation:

Parens patriae refers to a legal term that refers to the authority of the government to intervene on behalf of those who are unable to take care of themselves. The doctrine of  Parens Patriae has found its strongest use in the care of infants, mentally ill persons and those who are legally incompetent to handle their affairs. The State is the sole protector of all children under its jurisdiction, and the State courts have the absolute authority to interfere and protect the best interests of children whose well being is compromised by conflicts between parents.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.
