I've slowly learned that almost every single thing I learned in school and university was wrong, or else in some way majorly corrupted. No fields are spared as far as I've seen, besides maybe the practical ones like engineering (there's a market test for wrongness in engineering). Economics of course, but math (pure math, like analysis) and physics and linguistics and logic have severe fundamental issues that have a strong and far-reaching corrupting effect. It's just government funding and the power structure of intellectuals that allows them to equivocate and win by flashiness and the illusion of rigor rather than actual rigor.
There is absolutely no substitute for learning to think for yourself.
I've long held the opinion that the most important thing about todays system of schooling is not the content of the curriculum, but the structure of the whole activity in schools. Sort of like Marshall McLuhans "the Media is the Message" - it doesn't matter what is ON TV, what matters is that TV, as a medium influences thought and action in a certain way, regardless of what content is shown.
So what do our schools teach us? The first thing they teach you is that you are not the sovereign master of your time. They teach you that all your life, there will be predetermined periods of time, during which you have to be at a certain location, doing specific things. After that you will generously get some "free time".
Next thing you learn is that there is exactly one correct answer for everything and don't bother trying to come up with it yourself, we already have, so just memorize it.
And do NOT question authority. Mistakes are wrong, be afraid of mistakes, you will be punished for them.
All in all these places stifle creative thinking and personal development, reinforce conformity and submissiveness to authority. In other words they achieve their goal splendidly. What goal? George Carlin pointed it out years ago: the point of schools is to create obedient workers. Just smart enough to run the machines and do the paperwork and just dumb enough to passively accept all the rigged bullshit of this system.
When I abandoned university after a couple of years of
study getting drunk and partying literally every single soul in my environment thought it was a horrible idea. Parents, teachers, peers. No degree, no good job, no security, blah blah. 6 years later I still think it was one of the best decisions I've ever made. Now I'm self-employed, in complete control of my time and travel the world. I often wonder how my former classmates are feeling now about their "secure" jobs and their "necessary" degrees.
