The modern education system has no interest in producing critical thinkers.
It's interested in producing obedient slaves of the system, who, as George Carlin would say, are just smart enough to work the machines and passively accept it.
Having gone through high school and college, though not in it's entirety, I dropped out of both before going onto studying Political science, Philosophy, history and social sciences, I have a good understanding of this.
Young me, waking up every morning to the same shit that I felt like wasn't benefitting me, adopted misanthropic views very quickly. My teenage years of high school were reclusive with an increasingly large portmanteau of depression. I spent it playing music, engaging in activism, smoking pot and writing poetry. Long haired and unhygienic, I began to live what could be called a bohemian lifestyle. I viewed everybody as being a conformist, any sign (determinable by myself) that would have shown a sign of obedience received my outbursts of ridicule, critique and anger at what I considered 'Reactionary' usually in response to 'trend' followers which I considered pernicious and overall detrimental to humanity.
Everybody around me was wilfully vacuous and apathetic. I was once called schizophrenic for my activism and radiant political views! The person saying it didn't actually understand anything about politics or economics, not even the very basics, he admitted to not knowing what capitalism even was! Even when I explained that God didn't exist or mentioned politics, people were either immediately turned off and disinterested or had their fingers in their ears being absolute idiots speaking nothing but folly! I spent many years getting into science and religious study's, but eventually, though at whim, switched to politics and economy. People's ignorance angered me!
Skipping by the period of extensive drug use, travelling, acid, partying and sex.
I eventually settled down and continued my study's, still surrounded by the same environment, as I still am, I continued to house this fervent contempt towards ignorance and an eventual wish to entirely eradicate it even though the targeted audience had no interest in conceding or learning it went into a period of strong personal attacks to which I continued to troll them and ridicule them!
These people were jersey shore watching, trend following idiots deserving of hate and ridicule!
After around the 3 years of high school, having dropped out and spent years of heavy studying and still didn't understand mathematics and English that well (dyscalculia, English didn't seem necessary. It was more about the ideas then the way you actually pose them.) which led to me going for political economy and philosophy instead of science. I went to numerous education institutions where I dropped out until I went to a college that I also ended up dropping out of, why? Mainly because a lot of the "Teachers" looked down on pupils, they didn't expect anything but contumelious and apathetic temperaments and for this reason continued to keep alight a growing conflagration within me. As soon as I began my reign of meticulous and captiousness and persistent ramble about economics and politics, along with refusing to write anything to do with the class and Instead writing heavily critical pieces about capitalism. The "Teachers" had never seen such intellect within a student, it really showed how low their expectations of pupils were! This made me very very angry.
