Yes I agree with you. There will be possibilities of selling and buying of merits. So those who are higher in rank can benefit with this and so their friends. With this case, merit system will tend to be unfair. But anyway, there are also some who are righteous and fair to their fellows especially like me, a newbie, who are willing to give to those who deserve it. And they are the ones to be called a role model and are very much worthy of appreciation.
