there's two different things here. I asked about long term medians and talked about there being a fundamental shift due to change from single to dual income households.
so these dual incomes have pushed up prices and the long term medians along with them.
then there's the ratio of the two as a measure of affordability. I'm not estimating anything about how this would have changed over the years, that's your topic and you have said the affordability ratio would go down due to dual incomes.
