Final answer:
Tina is the one describing a marital equality issue, as she raises concerns about the fair division of housework with her husband Tony, which points to a need for more equitable sharing of domestic responsibilities in their marriage.
Step-by-step explanation:
The wife describing a martial equality issue is Tina, who tells Tony that it's not fair she does all the housework when they both work full time. This complaint highlights an imbalance in the division of domestic labor, a common topic in discussions of marital equality and gender roles. Tina's issue aligns with the concept of postgender marriages, where tasks and responsibilities are shared equitably regardless of gender, as addressed in studies by Risman and Johnson-Sumerford. Furthermore, this scenario reflects societal expectations and the ongoing negotiation of duties within a partnership, striving for a balance that respects both individuals' contributions to the household and professional fields.
