    That would be my guess as well, though I really don't have anything to substantiate it. However the graph shows prices really kicking off much later than this, and it's this time period I thought you were attributing growth to the rise in dual income households. If it's the smaller spike in the late 80's that you're referring to then fair enough - though it's only just breaking record highs in that period, doesn't seem significant enough to suggest a structural change or 'new normal' was established during that period.
