In The Two-Parent Privilege, Melissa S. Kearney makes a data-driven case for marriage by showing how the institution's decline has led to a host of economic woes—problems that have fractured American society and rendered vulnerable populations even more vulnerable. Eschewing the religious and values-based arguments that have long dominated this conversation, Kearney shows how the greatest impacts of marriage are, in fact, economic: when two adults marry, their economic and household lives improve, offering a host of benefits not only for the married adults but for their children. Studies show that these effects are today starker, and more unevenly distributed, than ever before. Kearney examines the underlying causes of the marriage decline in the US and draws lessons for how this trend can be reversed.

Kearney's research shows that a household that includes two married parents functions as an economic vehicle that advantages some children over others. For many, the two-parent home may be an old-fashioned symbol of the American dream. But this book makes it clear that marriage may be our best path to a more equitable future. By confronting the critical role that family makeup plays in shaping children's futures, Kearney offers a critical assessment of what a decline in marriage means for an economy and a society—and what we must do to change course.
