Alphas Allow Others Their Place
It is perhaps here that the absolute worst misconception about alpha behavior is made. It is also one of the fastest ways to spot a beta trying to ape an alpha. One version of this attitude is "I'm the alpha, I get the best, you get the scraps." Another version is "Everything is mine and you have no place."

Realize humans are social animals. We need other humans in order to exist. The nature of the social hierarchy is two-fold. One is so the greatest number of people can 'get by' in order for the group/species to survive (it organizes and protects the group). Two is it allows individuals within that group a place of security to obtain what that individual needs in order to survive.

Reread that last paragraph, it's THAT important to understanding alpha behavior.

The first reason is why the alpha looks out for the group. The second reason is why people are part of the group. And why they put their trust in the alpha, because he also makes sure that THEY can get what they need to get by.
