Please remember...these are not castes. They are not differentiated by the color of their skin and their line of work. These are Ethnic groups. There is a difference. Caste is a very wrong word to use.
Sorry, by caste i meant the desi meaning, i.e. zaat. Not the brown/black/white/green yellow orange burgundy castes.
