The lack of a central authority over English in the United States, at least, is related to a couple things. First, English is not the official language of the country. No language is. It's just a happenstance of our history that our lingua franca is English. Second, Americans, I think, would be really uncomfortable with the idea of a government entity controlling how people are supposed to speak and write. That lives too close to controlling what we say and think. Not that such an entity necessarily leads to 1984-style propaganda and thought-control, but we take First Amendment concerns very seriously here. Lastly, if you attend a specific school, you are subscribing to the instruction of that curriculum and those teachers. To have all students everywhere subscribe to the same authority of what they should know and how they should think... that can be pretty scary for an American.
