In the wake of vast social and economic changes, the nuclear family has lost its dominance, both as an ideal and in practice. Some welcome this shift, while others see civilization itself in peril—but few move beyond ideology to develop a nuanced understanding of how families function in society. This book draws on research from a variety of disciplines to offer a distinctive study of family dynamics and social policy. Concentrating on legal reform, it examines a range of subjects, including cohabitation, custody, grandparent visitation, and domestic violence. The book concludes that conventional legal reforms and the social programs they engender ignore social capital: the trust and support given to families by a community. Traditional families generate much more social capital than nontraditional ones, it concludes, which leads to clear rewards for the children.
