Another, less written about, issue with education is: overschooling.
All of these artificial thoughts and ideas are drilled into students heads; they spend something around 18-22 (in some cases 30+) years of their life living in a bubble unrepresentative of the real world; told to believe (and made to believe) things that are utterly irreconcilable with the "real world"; after which they are thrown out into the "real world" and told to "figure it out."
Overschooled, unprepared, unfulfilled. Instead of being given the tools and access to resources that would allow each "student" to make use of them only as necessary to achieve their goals -- they're all forced into mastering a set of tools that are almost always ill-suited for the individual pupil.
And after all this... living in a relatively sheltered, structured, naive existence: they've built up beliefs and mindsets that are quickly proven to be irreconcilable with the world -- and this identity and world view quickly beaten out of them by the "real world." Instead of being raised in the "real world," and been allowed to stumble about and learn to grow into it, and find their place in their formative, and most adaptive years: they're stuck in a false world for over 2 decades -- and unceremoniously dumped into the "real world" without the tools needed to navigate it. Sort of like living a privileged life since birth, and then by chance having it all whisked away and turned destitute.
Is it any surprise seldom few are satisfied with life? Utter barbarism.
