I know several kids who still believed in Santa Claus when they were in high school.
That aside, when your bodily functions are policed and restricted (girls not allowed to change their pads/tampons during class--as if anyone plans to bleed through a pad or tampon--kids in general not being allowed to go to the bathroom when they feel nauseous and then puking all over the floor, diabetic kids being denied going to the nurse to take their shots bc they arent allowed to have their supplies with them, etc... all things I've personally witnessed btw), when your ability to speak freely is heavily policed and monitored, when you can literally be bullied without consequences by a teacher if they're having a bad day because admin is on their ass or whatever and they do it all just because you're under the age of 18, and then taking into account how pretty much all anti-bullying policies post-Columbine (mostly/especially in the USA) have been awful and disproportionately punish disabled, queer, neurodiverse, non-white, and other minority students... yeah! Kids aren't gonna know how to fucking utilise the resources given to them because most of the time, they aren't built for them.
And then the teachers have the gall to act offended when these students don't know how to use the resources, especially when they're given the vaguest fucking directions on how to use them--further, when I have personally witnessed admin doing nothing for those students until way beyond when it would be beneficial (e.g. the student kills themselves or are murdered, moves schools, or just starts speaking out against the abuses). Also when you take into account how many schools are set up the exact same way as factories down to how admin functions just like a shitty HR board (source: I worked in a factory for nearly a year), you start to understand how exactly the system is not built to benefit students.
Of course, there are individual teachers trying to combat the factory-esque nature of schooling in one way or another, but it doesn't fix that the system itself is broken and serves to undermine students and teachers both--in areas of creativity, critical thought (esp in schools that still use standardized testing; memorizational skills over practical application skills), reading comprehension, etc.
