I think it's actually a very deep analogy to real fascist regimes. Recruit the type of poor who beat people up in bars via rhetoric that implies the rich are responsible for both their situation, and that behaviour. One implication is that the rich are the only ones who are exploitative, and the leader of the revolution in particular is not. "When we win, I will be good to you." Then you end up with a dictator.
At a meta-level the point is that the hyenas are the type of people who are insatiable, which is why they're persuaded by empty promises of power and why everything turns to wasteland once they're in charge.
But even then, conflict is a fact of life. If the hyenas hate you, allowing them to take charge will suck for you, even if it's nice for them. It's not a nice point but IMO it's an important life lesson.
