My national inflation calculator shows 19% inflation from 2002-2008. So if I get 50% off today is that 30% off adjusted for inflation? IE, my dollar was worth 19% more in 2002 when I could have bought a house for say $250k, ($500k bubble price in 2006) than it is today when I pay $250k (50% off bubble price).
If I could go back in time and take $300k with me, my $300k would be worth 19% more in that time; I’m still paying $250k for the house plus… I get the benefit of the left over $50k buying me 19% more goods and services. So I am wealthier in 2002. Thus, 69% off is needed today just to get back to 2002 wealth.
When wages fail to keep pace with inflation (which they have for 20 plus years) then even inflation dictates housing should get cheaper.
