Seattle had 12% unemployment in 1969, so I can't imagine things getting that crappy here again, because our economy is structured completely differently from the way it was back then. Then, Boeing was King - now, Dems can chase its HQ out of state to Chicago and not be hunted down and shot dead by the "people."
But then, we have always had a high cost of living, and over the past 15 years we've had fairly high unemployment rates compared to other places, except in places that have that simiar reliance on a major industry that we used to have with regard to aeronautics.
