The nuclear family offers married women some advantages: they have freedom from their relatives, and the husband does not have all the power of the family. Studies show that in nuclear families, men and women usually make an equal number of decisions about family life.
But wives usually have to "pay" for the benefits of freedom and power. When women lived in extended families, sisters, grandparents and adults helped one another with housework and childcare. In addition, older women in a large family group had important positions. Wives in nuclear families don’t often enjoy this benefit, and they have another disadvantage, too. Women generally live longer than their husbands, so older women from nuclear families often have to live alone. Studies show that women are generally less satisfied with marriage than men are. In the past, men worked outside the home and women worked inside. Housework and childcare were a full-time job, and there was no time for anything else. Now women work outside and have more freedom than they did in the past, but they still have to do most of the housework. The women usually have two full-time jobs, and they have not much free time.
Who used to live together in an extended family？
