What requires people to perform duties or their caste?

In many societies, the concept of caste dictates specific roles and responsibilities based on hereditary status, often tied to traditional occupations. This system can enforce social order and continuity, compelling individuals to fulfill duties associated with their caste. Additionally, cultural, religious, and societal norms may reinforce these expectations, leading people to adhere to their designated roles out of obligation or fear of social repercussions. However, modern movements challenge these restrictions, advocating for individual choice and equality.
