Gee this is a tough and probably depressing question. When I was a little kid and we dominant the weak teams then were Melb and South and Fitzroy.
I remember thinking that they were so bad that I wouldn't see them win a flag in my lifetime. So, thirty years later Fitzroy are gone, South are gone (Does the Syd flag count?) and Melb have played in a couple and lost them both badly. Saints look good every few years or so, but haven't won one either.
At the moment a lot of the teams that were sort of on a par with us a few years ago seem to have gone past us: Hawks, Geelong, Bris, Carlton, Ess and maybe even Melb.
Who has slid past us? maybe North, time will tell.
So in the short term, say up to ten years, it doesn't look too good. And after that is anyone's guess.
