Final answer:
The wife's extra workload, despite a belief in gender equality, exemplifies their traditional gender roles. This scenario is a common reflection of cultural norms that disproportionately assign housework to women, which persists even in the context of stated equality.
Step-by-step explanation:
A husband and wife report that they believe in equality of the sexes; however, the woman does most of the housework. The extra work is an example of their traditional gender roles. Despite both external jobs and shared beliefs in gender equality, the disproportionate domestic workload suggests an adherence to traditional norms where household responsibilities largely fell to women. This condition has been historically prevalent and continues to demonstrate the persistence of these roles, even in the context of stated egalitarian values.
Indeed, numerous studies have confirmed that, on average, women carry out a larger share of unpaid domestic labor, such as house chores and childcare, even when they are also contributing significantly to the family income. This pattern reflects the deeply ingrained nature of traditional gender roles that are transferred through generations and cultural expectations. The fact that women often face a "second shift" upon returning home from paid work illustrates the ongoing imbalance and the stress associated with juggling multiple responsibilities.
