However, there's an element not discussed. And that is, reservations at B-schools or for that matter at engg colleges dont matter !
Say, u r a private recruiter...u come to IIM-A and have a number to recruit in mind. You are told that there are only a 100 odd candidates left. You, having heard all the hoopala abt reservations in B-schools are forewarned that many of these would be the SC/ST candidates who did not reach here on their own merit. U interview them. What do u find? That the candi9dates are actually sub-par. What do u do?
Of course, nobody is forcing you to recruit from IIM-A. U go to MDI or XLRI to get the candidates u require. Ur work is done. U get good candidates.
So what happens? The good candidates still get the jobs that they deserve. The recruiters get the candidates they wanted. The only losers in all this would be the SC/ST candidates who'll develop a complex seeing others get such good placements and they having to search for off-campus placements and govt owned companies...this because, its empirically proven that currently most SC/ST candidates are recruited by companies like SBI, ONGC, HPCL etc.etc....all PSUs, who already have to recruit the requisite no. of SC/ST candidates to satisfy their requirements of quota candidates but now will have to recruit more of them further lowering their competitiveness.
However, of course, the situation would completely change if the private companies too are forced to recruit a requisite no. of SC/ST candidates at all levels. It would affect their competitiveness and also disprove all I wrote above. However, with the growing clout of huge conglometrates like Reliance, Tatas, Birlas...I dont believe that'll ever happen. All that shout about reservations in private companies is just that...shout, to garner votes. The govt can easily change reservation requirements in govt owned bodies but never in privately owned cos.
And yes, who also gains? Colleges like XLRI and MDI who might not have hoped of getting those cos on campus earlier !
Disclaimer: May I reiterate that when I say SC/ST candidates, what I really mean is any candidate who got thru and who didnt deserve to be there.
