Final answer:
Blue-collar families may emphasize obedience in their children to prepare them for similar occupations, reinforcing career inheritance and perpetuating the class system.
Step-by-step explanation:
Blue-collar families often emphasize obedience in their children because their jobs, which tend to involve following orders and performing repetitive tasks, benefit from such behaviors. This emphasis on obedience and conformity can be understood as part of a broader process called career inheritance, where children are socialized to adopt similar occupations and roles as their parents. Through this socialization, children are taught to internalize behaviors that are valued in their parents' professions, thereby perpetuating the class system. As sociologists suggest, this is why blue-collar families may stress obedience to prepare their children for similar blue-collar work.
