That's the kind of thing that seems happy in retrospect, though. Kids don't appreciate many of the benefits of youth until they've lost it, and until then, small dramas and angst can often have an exaggerated significance.
Frontal cortex is associated with high level reasoning: the interpretation is that while teenagers are able to resolve the same sorts of issues as adults, they're spending a lot more mental effort to do so - it's taxing. Hence the phenomenon of teenagers tending to oscillate between "mature and capable" and "complete breakdown" when the stress gets dialed up (not that this doesn't happen to adults, but relatively we handle more better).
Not unsurprisingly, the frontal cortex is also one of the last regions of the brain to undergo maturation: the neural remodel you get at the onset of puberty starts from the back of the brain and moves forward.
In short: adults take an observation of adult-like behavior at face value and presume it implies adult-experiential reasoning, then get surprised and angry when the environmental stresses suddenly collapse the entire facade.
I’m not so sure about the “zero responsibilities” statement, either. If I didn’t do my homework for certain classes I would be punished with something similar to solitary confinement.
I started work at 15, so no responsibility-less loitering for me. And those hangovers can only happen if you save up enough cash after paying for school lunch and car insurance, which the 6-month cost was about the same as the price of my car $1000.
My guess is that the "happy" sample size came from the Kardashian/Jenner family. Given that they have a lot to lose here, I would think, as well.
And yes, I technically got "free" lunch, but do you want to be in THAT line? I mean, the cool kids are in the subway and burger line for a bargain of $6 a lunch... So why wouldn't I do that, too?
Thank goodness I didn't have an incessant window into all their lives outside of school, while I was working 30-40 hour weeks at 7/hr.
I can definitely see that if you hoist adult responsibilities on kids it’s super stressful, but that is not normal everywhere.
