The New Guinea Big Man, for example, gains his status primarily as an organiser of feasts and dances in which his own group competes with others, and as a public orator on such occasions. He attracts followers by his force of personality and his political skills as an organiser and diplomat in dealings with other groups, and can certainly behave despotically to those at the bottom of society, the ‘rubbish-men’. But while he obviously enjoys his status, he is accepted and regarded as a legitimate leader because he is seen as an essential asset by his group of followers, and in my experience tends to be gracious and polite.It's not about being a bully. It's first and foremost about being an asset to his subordinates and being a man they want to follow. Everything else flows from that.
It is interesting to note that even primitive societies have developed the concept of the Omega as well.
