Yes, but for whose definition of "educated"? In the US, at least, the government was not supposed to decide that. Individual families and communities were. And, as I have posted elsewhere in this thread, the people who set up the US system of widespread, compulsory public education were quite explicit about what they meant by "educated", and that included plenty of things that any reasonable person would consider to be indoctrination, not education--and that was on purpose.
