Was just woken at 11:30 our mountain is burning and has gotten worse.

Not sure why you split per capita and average household .
And the average home price of $450k means that some are 1,000,000 and some are $200,000.
I do agree with your sentiment about homes costing too much but that in my opinion is due to tax policy that encourages using homes as commodities vs for living in . Corporations owning 100,000 houses or individuals owning 10,20,30 homes does not help affordability.
That's the point, averages are really useless, & are not indicative of the condition of the economy. Watch the movie 'The Big Short', while it's a product of Hollywood & seriously downplays the role of FreddieMac, FannieMay, USDA Rural Development,...shows how property values can be based on fabrications & speculation more than actual value,.....with the BlackRocks of the world running around paying 150-200% of a listing price(& I know You know that), I give -0- legitimacy to #'s like those being grounded in reality. That is all Sir....
