I don't think Thatcher is irrelevant at all, Blair took New Labour down a Thatcherite path, we've got a Thatcherite PM in power now, the Falklands is still disputed territory, the Unions have never regained the strength they once had and she started the process of privatisation which is still ongoing today, it's hard to deny that she still has a lot of relevance in the political world

Edit - oh sorry, you mean culturally, hmm I'm not really all that sure about that, I don't know a lot about what life was like for most people back in the 80's
