I am addressing the questions asked by my friends related to this issue and relevant news articles over twitter, facebook and email. Feel free to correct me where I am wrong.
Basis of Reservation ?
Available data shows that the demographics of people in power is not representative of the overall demographics. This is attributed to the discriminatory caste system prevailing in the country. So a system to ensure equal participation was put in place by devising a system called reservation or proportional representation system.
Is reservation anti-merit ?
If mere marks were to judge merit, we have to look beyond just marks. Experts acknowledge the limits of current exams and the opportunities to learn and coaching determines the scores rather than just individual ability. Unless opportunities are equal, exams cant be a real test of ability.
