How can people move into a different caste?

In many societies with a Caste System, moving from one caste to another is challenging due to deeply entrenched social norms and discrimination. However, some individuals can change their caste through social mobility, which may occur through education, economic success, or inter-caste marriage. Additionally, legal reforms and affirmative action policies in some countries aim to reduce caste-based discrimination and promote equality, allowing for more opportunities for upward mobility. Ultimately, while change is possible, it often requires significant societal shifts and personal perseverance.
