Describe the caste system in India?

There are five levels: Brahman, Kshatriya, Vaishya, Shudra, and Harijans. Each of these castes is referred to as a jati. People are expected to live the entirety of their lives within their castes; there is no change in fate. This system has been enforced in India for ages and has instilled a sense of expectancy in its people.
