Why is nuclear family ideal for modern industrial societies?

The nuclear family is often considered ideal for modern industrial societies because it promotes efficiency and mobility, allowing members to adapt to the fast-paced changes of urban life. This family structure typically consists of two parents and their children, facilitating a more focused environment for child-rearing and resource allocation. Additionally, the nuclear family can easily relocate for job opportunities, which is essential in an economy that values flexibility and individualism. Overall, this arrangement aligns well with the demands of modern economic and social systems.
