This article is why, although I love teaching and at this point consider it my career, I probably will never be a classroom teacher in my home country. That's not to say I don't face these kinds of issues in Korea, but being a "foreign" teacher here insulates us from some of the administrative "BS" regular teachers face, and, undeniably, it insulates us, too, from some of the (poorly targeted) responsibility that gets heaped on the typical homeroom (i.e. locally-native-speaking) teacher.
I like the term "Education Malpractice" as used in the article. I don't claim it isn't a problem, here in South Korea, as well, but here, unlike when I was teaching in the US, I get to sit in my privileged position as a foreigner and look the other way with respect to a great deal of it.
