Yes, it's always easier in your own country, isn't it? I remember that's the case in the US too, perhaps because it's the dominant language. But of course English is a foreign tongue here and the assumption of the systems in place is that the teachers of foreign languages will not be native speakers of them. In Finland there are occasionally people hired as native speaker teachers of foreign languages without formal qualification in the language in question, but to work in an official kind of school you need a pedagogical degree and usually a master's (but occasionally a bachelor's) in the subject area.
