Hence the old saying, Vek.
Absolute power corrupts absolutely, regardless of whether it's an alpha male posturing and preening himself in front of everyone just because he feels like it or some third rate hack looking to make his mark in the world because no one respects him; much less the alpha male.
But let's look at it in a more descriptive stance.
So what does the hack do in order to gain his fifteen minutes of fame? He goes out and tries to find ways to gain his foothold, build up and expand his influence on others until he finds himself sitting on top. How he goes about it is entirely up to him, but there are two pathways as to how one can get to the top, but they do have a reversal of fortune tied to each. One, they undergo a meteoric rise because of some one-hit wonder type of deal, but they fizzle out just as quickly after some period of time. Two, they build on their influence slowly, but they don't gain their notoriety as quickly and eventually disappear into the void as if they were never there to begin with.
So now that the third rate hack has now become the big cheese, where does he/she go from there? Well, this might come from someone who doesn't really have a complete grasp of psychology nor do I make myself out to have an Associate's Degree in the field, but here's a theory.
They will only want to go after more and more things to sway under their influence so they can maintain their control on the general populace. It could be anything, like offering refunds on valid purchases, increased tax credit on buying a specific item or - as I recall from playing numerous sessions of Romance of the Three Kingdoms - bribing someone to switch sides or virtually anything else within their limitations of logic.
And the vicious circle begins again with a new pushover deciding he/she had enough of the current power structure and decided to do something about it.
Again. Same concept.
Could it be because those that have the submissive trait have become agitated by those in power? Well, that's kinda hard to say. You can't be led around by wimps as you could with a rampaging psychopath hellbent on spreading his influence everywhere with brute force, so you're pretty much stuck with the lesser of two evils. The problem is, with a situation like that, who do you go with? The wimp because that person might have a carefully planned idea or the alpha dog because with extreme knockabout physicality, anything can be accomplished?
