As we’ve become richer, we have moved from farmer toward forager values. This has made us more egalitarian – we are more averse to inequality and domination, and more uncomfortable when people brag, give orders, or act overtly as if some people are much better than others.
On the surface, our stories tend to affirm our social norms. Villains are often greedy disagreeable unstable illicit dominators, while the heroes who oppose them are often modest, agreeable, and capable, but not assertive or aggressive.
However, not all is as it seems on the surface. For example, we are far more interested in seeing drama or action shows centering on theses kinds of jobs: police, soldiers, doctors, lawyers, scientists, chefs, actors, athletes, and musicians. These are jobs where extreme outcomes are more possible, either because big harms can be avoided, or because great status or honor might be gained.
In jobs with more extreme possible outcomes, we are more comfortable with overt inequality and domination. We are more ok with the capable doc getting explicit deference, and berating the incompetent doc. Or with junior chefs saluting “yes chef” like soldiers. Or with the super musicians not giving much consideration to the grips and groupies who serve them.
We are not only more ok with such overt inequality and domination for these jobs in real life, we are also more ok with it in fiction. In fact, you might well say we relish it. Just as little girls fantasize about being a princess, or little boys fantasize about being action heroes, we all like to imagine we are the more able workers shown in these stories. We like to imagine getting the status and deference that these fictional characters are shown to be justified in getting.
Of course we prefer to paper this over with a villain who is far worse, making our heroes look great by contrast. So we can pretend that what we really want is to bring down the arrogant. This is somewhat like how we like stories that titillate with sexual or other indulgence, but then pretend to endorse a morality tale where such behavior is punished in the end. In both cases we can enjoy a fantasy of vicariously experiencing pleasures, while officially pretending to disapprove of them.
TVTropes has noted the hypocrisy.
In the new Disney movie Big Hero Six,
[spoiler warning]
everyone thinks the mask-wearing super-villain is probably industrialist Alistair Krei, because he seems to fit the villain stereotype of "greedy disagreeable unstable illicit dominators", but it turns out it's not him - it's Professor Callahan, who didn't actually die in the fire and has been holding a (quite understandable) grudge against Krei...
