Do you know wife of Ambedkar ? she is a brahmin lady, and he had written while providing reservation, the reservation has to be verified every 10 years and it should be extended if needed, the reservation in former days done only for to bring backward caste to be educated, and to know about the world, that is y they had given the reservation, Now one backward ministers son will be getting reservation and grant for studies, at the same time the minister uppercaste (subordinates )car driver's son or cook son has to pay fee for the studies, so we need only economic reservation not caste wise.
