Caste syatem is the biggest curse this country has. Why not provide within the maximum limit cap of 50% Quota(for SC/ST/BC/OBC, etc) as approved by the Supreme Court, a total of 20% reservation within that for People of mixed caste or mixed religion parentage. Over a period of 25-50 years this can be INCREASED to 30-35%. Thisis the only sensible way to pull out the country from the morass of class, caste & religious difference
