Dickens was a cheap novelist, a pot boiler, in his time. Respected writers, whose names I can't seem to recall, wouldn't give him the time of day. Do you realize that the first four HP novels are still near the top ten on amazon?
If the HP books were written in current teenage slang, with references to current events or current culture, I would expect them to fall by the wayside, but they aren't. They are written in standard English and carefully avoid topical references.
Your definition of great literature may be correct by university standards, but Gone With the Wind still outsells most literature. So does Agatha Christi. So don't expect HP to disapear anytime soon.
Dickens helped to bring about compassion for the poor. I wonder what Harry Potter will help bring about in society? There will always be cheap novels; the problem is that good literature currently is sadly lacking, particularly for the sensitive younger mind. Too bad something other than witchcraft isn't the current rage.

I don't. Unfortunately
