Yes - that's why it is undemocratic to give quota to any section of the society.
The main purpose of quota is to bring social justice to the poor. so to bring them up, free education and free higher education can be provided. If we don't do that, then even if we have quota, the poor people won't be able to reach the stage from where they can reap the benefits of quota. Instead, the creamy section of SC/ST/OBCs would continue the avail those benefits and fatten-up. With Quota-system in place, the main purpose of quota would be defeted.
