I generally agree with your criticism of the education system as an instrument of filtering/segregation but I would argue school has some practical value. > Three - grade people into quality batches, based off their punctuality and ability to perform meaningless tasks to arbitrary and meaningless quality standards For example, doing math is a useful skill, not a meaningless task. > Four - because the management has gone though the same system of education, the pupils must learn to read through poorly worded vague instructions and understand what their superior actually wants to see, even though they are not capable of expressing it clearly. Poorly worded exam papers serve as good training There is a lot of nuance to English communication, at least among native speakers. Things like active/passive voice, hyperbole, and different kinds of logical arguments are implicit to communication in professional circles. It's important to study them. Also you're ignoring the cultural education that studying literature/writing provides you. There are tons of literary references in everyday communication and you will be at a disadvantage if you don't know them (a "Scarlet Letter", "Big Brother", etc.). These stories are foundational to Western culture and you are expected to know them.
