Ask the general category students about it and they will tell you how they are deprived of opportunities because of quota system.
For those unaware of quota system in India, in easy words, it is somewhat similar to this analogy-
There is a 100m race. 'General' category, SC/ST category, OBC category participates in that same race.
For General category start line is a 0 mark and finish line at 100m mark. For OBC start line is at 10m mark and finish line at 90m mark. For SC/ST start line is at 20m mark and finish line at 80m mark.
This makes it easy for an OBC, SC/ST to enter in any top university they want. It is after entering the institute, they are unable to cope up with the rigor and fail or drop out. That is when this "victim" picture is painted by them. Ask an IIT/NIT/IIM/Doctor/IISc student in your circle about it and they will tell you the other side of the story.
Successive Indian govts have taken several measures to ensure they are not deprived. Today the scenario is that if a general category person, even by mistake, calls them out with certain words, there is an instant jail with no provision of bail.
