FWIW, my mental CAD/USD price anchor was set when I was coming of age at 0.75 CAD / USD. Today it at 0.73 CAD / USD, and I've seen it touch 0.60 ish and pass parity in my lifetime.
IMO: 30 years isn't relevant to look at, because its ancient history (I'm calling both of us ancient here). It pushes back too far beyond 2008 & the GFC to capture data that isn't relevant to the modern global economy. Everything about everything about the world, today, is a consequence of the GFC, and its likely that by the year 2100 we'll still talk about it as among the most significant things to happen to the world in the past century. Maybe the most significant.
