Meritocracy means your elevation within a group is not influenced by your ancestory, wealth, socail status, who are your friends with, how much you were/are-being oppressed, charisma or twitter followers.
The group has a mission. You help with mission, you go up. You work against the mission, you go down. Thats meritocracy.
