Krishna has 10 kids and went out of country for 10 years leaving behind a huge source of food. Two of his kids started dominating others and started to eat most of the food in the house, leaving the other eight starving to major extent. The eight kids become weak, so weak to the extent that they could not even eat what they were supposed to eat. If this continues, they will eventually starve to death. His father returned home. He ordered the two guys can eat upto 50% of the food and leave the rest to 8 guys. ofcourse the two will be affected temporarily, as they each use to eat 40% of the total food. Is Reservation bad ?
