The average household income is 80k(ish) the average house is 420k(ish)
In Bethlehem, PA (a fairly middle of the road place tax wise) that means $5050 take home pay a month and a mortgage payment (FHA 3.5 down, 6.7 interest) of $2650 a month. That is more than half your pay just on a mortgage, not pmi, not insurance, not utilities, not anything else. Do this calculation across the country with localized numbers, do it with rent instead. Add a car and insurance for it into the mix. Then try adding in health insurance, groceries, etc. You are going to find that the numbers result in average people being squeezed and guess what? That lines up with peoples actual experience.

My interpretation of this is that pay has not kept up with inflation.
