There's a website focused on problems with schooling system in the US. that explains a lot of what happens behind the scenes in the education system. Although it's US. based we have very similar problems all over the world. Your suggestion about education being "one size fits all" is particularly relevant.
The website is called deliberately dumbing down

I'm on the verge of pulling my kids out of school and home schooling them, school isn't about education anymore it's about indoctrination. In hindsight, it was when I was going there too.
