Explaining the pattern of racial segregation of manual scavengers by yours or some other's cases is nothing but deliberate misinterpretation of this matter. We are not discussing SC/STs here; The center of the subject revolves around the untouchables. Even today, although SC/ST has gained some sort of economic freedom in some patches of India in an independent fashion marriage alliance is still not a common phenomenon anywhere in India. Even in the states that enjoys most economically liberated economies, how many belonging to higher castes have been seen getting into a mutually accepted family alliance with a member of a manual scavenger's family? Capitalism, as it is being stressed upon as a savior of the "economically oppressed" untouchables did very little part in removing socio religious bigotry in Europe as the revolutionary movements inspired by political, social consciousness did.
