English-speaking countries are not all alike. The level of non-English speaking immigration to a country (which happens in all English-speaking countries, but to a much greater degree in some than others) has a large impact on the ability to maintain high standards for the language.

As I'm sure you know, English spelling is also much less phonetically obvious than Italian (and I would not be surprised to learn that English is slightly grammatically more complicated than Italian, although frankly, as far as I'm concerned, any language with grammatical gender wins for difficulty), so emphasizing correct writing might be slightly harder.
