The only place where reservations make any impact is areas where there are too many good candidates and somebody from the lesser privileged sections of the society who is equally good can't make it due to the limited availability of opportunities. In such cases it makes some sense to offer the minorities a degree of reservation as the culture is unwelcoming to a meritorious minority person.
Any thing apart from this and what you will see is, the social problems remain totally unchanged. Reservations and quotas means some one from privileged class who is deserving of a position will be denied the opportunity, and some one oppressed class who is not deserving will get the opportunity instead. The net result is the whole system will be poisoned. Work never gets done, more and more hard working people are denied opportunities. At the same undeserving people get the same opportunities and make a big waste out of them.
If some one is good, they will win anyway. If they are not, they can't and won't.
Our job is to create a level playing field. So that anybody who want's to, can deliver.
