The schooling system as we know it was certainly set up to create better workers. Back when the industrial era started it wasn't a bad thing, because this was the first time that the working and poor classes were actually taught anything like literacy and maths to elevate themselves at all. However, over the years things have changed and while many may still be happy to be basic level workers, more people are aspiring to be more than that and have the capability to be more than that if they could only have a bit more freedom to choose the direction of their education.
Welcome to Hive, by the way. I've just been reading about your move to Seoul. What a time to be setting up a new life in a new country! You are braver than I. I'm currently locked in Australia, but in many ways it's less stressful than trying to navigate all the medical and tracing demands of relocating. Glad my relocation was 13 years ago. Even our visit back to the UK 9 years ago had more security hoops to jump through than our initial move. I dread to think what it must be like now.
