Even a casual observer of American politics might notice the importance of family in political rhetoric like the Republicans' "family values" and the Democrats' "working families," but we know surprisingly little about the role of family in American politics. We typically think of family as "private" and out of the public realm of politics or we associate family and public policy with so-called family policies, such as welfare or family leave. The goal of this book is to clarify the relationship between seemingly private family life and federal public policies. It asks two important questions: How do policymakers employ the concept of family in the policy process? And, what are the consequences of employing this concept broadly in public policy? All in the Family is the first empirical study of family in the American policy process. It shows that, far from being "private" or only a part of "family policy," family is an important part of American policymaking even in seemingly "non-family" policies like immigration, tax, and agriculture. Policymakers rely on family to determine eligibility, distribute goods, and provide justification for their positions across a wide range of policies. Ultimately, this book shows that seemingly private life makes American public policy possible, and it suggests that the ability of policymakers to accomplish their goals is intimately tied to the strength and organization of American families. Yet, it also demonstrates that relying on a dynamic institution like family can have unintended consequences, potentially destabilizing policies over time.
