“Infosys mentor against caste-based reservations”:http://www.sulekha.com/redirectnh.asp?cid=307585

bq. It [the reservations] cannot be based on a certain caste. It doesn’t matter to what caste an individual belongs, as long as such a person or his/her family is handicapped because of resources…I think they alone deserve to be considered for reservation, be it in education or employment, Murthy said.

Only a politician who does not want to be elected again will remove caste based reservations for Govt. posts. If you read Krishna’s statements in the same article, you can see that he wants caste based reservations even in private sector.
