Sounds like you're describing was what Americans call affirmative action ("a reservation system so that people belonging to those castes could get jobs/education/opportunities"). I am not knowledgeable about India's system, but I get the impression that like the one in the US, it is politically/culturally divisive and I would take any comment about it as opinion/preference rather than fact.
