Caste is a disease that affects people of India in different ways. It treats its victims differently from its beneficiaries, but the preamble of the constitution of India endorses an undifferentiated fraternity. Though we are all Indians, caste does not allow us to live with the single identity of being Indian. You can find people of assigned different social status - inferior to superior - depending upon their caste. Dr. Ambedkar argues "People divided into thousands of castes can never become a nation". Caste divides people by birth, and until you die that disease does not allow you to free yourself. Fatal diseases such as cancer, leprosy etc., can be treated or controlled with proper medication, but the caste disease has no treatment because the pride or shame of a particular caste sticks to it throughout its life. Hence, we are divided as a nation.
The upper castes form the privileged elite who enjoy ownership of land and therefore are more powerful economically, politically and socially. They dominate Indian society, more particularly in the villages, and hence village social structure is the biggest hurdle for Dalits in India. The term 'Dalit' itself divides them from the upper castes and so their houses are also outside the village as they are considered impure, and some people tell them, "You must have done something really bad in the past, therefore you are suffering from untouchability." Upper castes have separate wells and temples which no dalit is allowed to access. There are still some places in India where Dalits drink water from separate containers, are not allowed access to education, or to walk on the street with shoes. The untouchables are called by different names i.e. Bhangi, Mahar, Chamar and are also a target of derogatory labeling because they are seen as dirty people. In the movie Fandry they are called as fandry (Pigs). Dalits work under the privileged upper castes, on their farms, in the villages, as daily wage labours; they are forced to do low-grade jobs.
