Posted link is from The Atlantic, article written by James Hamblin, MD, quoting research from UCONN sociologist, Christin Munsch, Ph.D.
As couple/family therapists, we talk to couples frequently about how they are negotiating the roles of breadwinner and homemaker/parent. The article/research, based on the word of married 18-32 year-old participants who contributed to the study between 1997-2011, implies that men making significantly more money than their wives may suffer health problems from the psychological effects/anxiety related to being sole/dominant financial caretaker for their families. The same dynamic does not seem to apply when wives make a bigger salary than their husbands, concluding that possibly earning may be seen more as an opportunity than an obligation by females.
While there is a large context with multiple social changes occurring in gender roles between 1997-2011, it seems the research would support moving away from a strictly gender-based division of labor to a more egalitarian sharing of both obligation and opportunity with career and child-rearing. This trend toward “sharing” may involve more communication about what assumptions each partner may have about gender roles from their families of origin, and how they each hope to contribute to their partnership. It is unclear whether the anxiety that affects health comes from perceived disparity, or a sense that there has not been a voluntary commitment to their role. Always more research to be done!
