Hey, I'll be 44 on my next birthday and I've lived in the UK for almost fifteen years. From my perspective, it's changed immeasurably during that time, the encroachment of American culture and globalisation in general the cause of much of it.
I feel the rate of change in the wizarding world would be relatively slow, however. It's a very, very old culture that had remained separate from the Muggle world for centuries. I don't think a handful of teenagers, however heroic and lauded, are going to radically change it into an unrecognisable place. It would change, but slowly and in its own way, rather than a way that mirrors the real British world. The Wizengamot is not Parliament, Quidditch is not cricket, although they may have been created as social satires of such.
