I think your point about YA fiction is a really good observation, but I disagree with The Hunger Games being used as the prime example because I don’t think it really ever embraces the “chosen one” prompt – or at least if it does so, it does so in very specific ways.
I think that The Hunger Games, or at least the later two books is about being a symbol and being perceived as somewhat of a “special” person without actually having the power of one. Throughout the series, Katniss and her peers are constantly being paraded around by both the government and the resistance as these larger-than-life figures that are at alternate timers either trying to quell a rebellion or feed it. They very rarely, however, have any agency behind the scenes and are most often knowing puppets for whichever side happens to have control of them at the moment. When they are actually given some sort of agency, most notably in the fighting sections, often very little happens as a direct consequence of their actions, but instead are filtered through state or rebel media sources and used to one side’s advantage in that way.
With this in mind, that series becomes a lot more about finding ways to enact change within systems outside of your control. Furthermore, I think something central to the series’ philosophy is that the presentation and symbolism of an action matters a lot more the action itself. As such, the only way the protagonists find to actually enact change is through small subversions of their public image. That still might map to the high school metaphor. Appearance is very rarely more important than it is in high school, and it’s also a place where norms on speech and action are often strictly enforced, but I think it maps in a slightly different way than at first blush
I’m pretty sure I went on a rant only tangentially related to the post so I’ll go ahead and wrap it up.
