You can allow a horse to breed by giving proper atmosphere. But no matter whatever you do, you can not breed a mule. Sorry if it sounds rude but in simple term you can not gain anything from reservation. It has been over 60years that the reservation policy has been going on. Poor people are still poor, perhaps poorer. A farmer dies out of hunger. A SC/ST student has been still struggling to crack IIT with poor score. Whereas a brilliant no-caste student has been denied admission to an ordinary University! This is what the reservation is all about. It is good for no one but the incompetent cowards.
