Absolutely, I agree. No group, every ruling structure benefits from the ignorance of the masses. I was replying under the impression you are arguing against the need for everyone to be properly educated (in the sense of high level of literacy, critical thinking, reasoning etc. all the things PISA is supposedly designed to measure). I apologise if that impression was wrong. It's true that I was a little confused by your post and the one you were replying to, mostly because of no fault of yours or the parent's but because I'm not entirely sure what the percentages of "highest scientific performance" that the article is referring to mean.
