In this month’s lead essay, historian Stephanie Coontz, author of Marriage, A History: How Love Conquered Marriage, briefly lays out the history of marriage to understand its present and future. “Today, when a marriage works,” Coontz argues, “it delivers more benefits to its members — adults and children — than ever before.” However, “the same things that have made so many modern marriages more intimate, fair, and protective have simultaneously made marriage itself more optional and more contingent on successful negotiation.” Instead of trying to resurrect a bygone ideal of marriage, those of us interested in encouraging healthy families now need to focus on what makes unmarried co-parents, single parents, cohabiting couples, as well as contemporary marriages successful on their own terms.

Kay S. Hymowitz, the William E. Simon fellow at the Manhattan Institute, argues that Stephanie Coontz’s sketch of the state of marriage is badly incomplete, failing to acknowledge the class divide in marriage and childrearing. “This marriage gap,” she writes, “has profound implications for our political, social and economic prospects for one simple reason: overall, children do better in life if they are raised by their own married parents.” According to Hymowitz, “The de-linking of marriage and childrearing is a particular dilemma in the Unites States … [W]hat you have is a recipe for entrenched, trans-generational poverty, inequality, racial disparities …, reduced social and economic mobility, and — libertarians take note! — demands for government taxes to fund programs to correct the mess.”

Betsey Stevenson and Justin Wolfers, economists at the Univesity of Pennsylvania’s Wharton School, “re-frame Coontz’s careful history of the family in the language of economics,” exploring the economic forces underlying changes in marriage. Modern marriage, Stevenson and Wolfers argue, is marked by “a shift from the family as a forum for shared production, to shared consumption.” Modern marriage, which they call “hedonic marriage,” is more centered on love and companionship. Marriage as such isn’t doomed, they claim, but “marriage in which one person specializes in the home while the other person specializes in the market is indeed doomed,” especially as women’s educational levels begin to surpass men’s. Attempts to “re-regulate” the family to fit a classic ideal, they argue “may actually be a force undermining the dynamic institution that is the modern U.S. family.”

In his reply, University of Texas sociologist Norval D. Glenn, identifies Stephanie Coontz as a member of the “family-change-is-irreversible school of thought,” which he says “includes the view that attempts to retard, stop, or reverse any major aspect of recent family change are futile and thus are at best a waste of effort and at worst downright harmful…” But, Glenn asks, don’t liberals generally think policy can mitigate the consequences of economic change? Moreover, is anyone really asking to return to some Golden Age of marriage? There is evidence, Glenn submits, that marriage trends will further improve and that policy interventions, like marriage education, can help.
