Interesting claim. Let's look into it.
Average home price in 1970: $25k I found a few different figures on this one, and averaged them out.
$25k 1970 dollars in 2026 per CPI: $220,251 https://data.bls.gov/cgi-bin/cpicalc.pl?cost1=25000&year1=197001&year2=202604
not necessary, but gives context: Average (not median) home price today: $502k https://fred.stlouisfed.org/series/MSPUS
Median home price today: $410k https://fred.stlouisfed.org/series/MSPUS
"The median money income of all families in 1970 was about $9,870" https://www.census.gov/library/publications/1971/demo/p60-80.html
Median family income in 2024 (most recent year reported): $105,800 [note: does anyone believe this? FRED is claiming median family income went up 45% in the past decade and I find that EXTRAORDINARILY suspect. Few people get COLA over 3% and many getting fuckall.] https://fred.stlouisfed.org/series/MEFAINUSA646N
roughly a 10.7X increase
My best guess is that Mr. Brooks, using slightly different numbers (sources vary, exact years, etc...), to arrive at: 1970 Home Price + Flat Income Gains = $138,000. This is not great methodology, as growth is looked at in percentages for a reason. To illustrate, suppose instead of a house we were looking at candy bars. Let's say in 1970 a candy bar was a dime and today it's $2. Grafting raw wage gains onto candy bars, we're saving over $80k on each candy bar!!! Oh wait, that's silly. Let's stick with percentages.
Using the official wage numbers, we arrive at "the average home today would be $267,500". This is more accurate yet still a massive departure from where we are today.
So... what actually broke?
There are several explanations for this divergence.
The Good: Houses today are bigger and have better construction standards. Please, before you start typing a survivorship bias based claim about your house from 1905 that's still in great shape today, read up on survivorship bias. Yes, there are modern builders who do shoddy work (we've all seen the Youtube videos), but overall a house built to code in 2026 is significantly more advanced. A fair amount of the cost increase can be captured here.
The Bad: Rent seeking. Figurative and literally. Somehow someone was like "hey, I'm going to get rich by making a basic necessity worse" and nobody beat them within an inch of their life to discourage others. Rookie mistake by our society.
The Ugly: Official numbers are suspect at best. This was true before 2025 and whoa boy is it true now. Inflation is chronically under-reported BY DESIGN. That means actual inflation is driving up the cost of houses and cans of bean and things, while reported inflation is being used to determine your pay raise (that is, if you even get one). This divergence that started in the 90s is hitting critical mass here in the roaring 20s and we're probably fucked as I haven't heard anyone in a position of power even recognize this problem, let alone suggest how to fix it.
