> So, the inflation figures under represent the cost by a factor of 3.5 over those 80 years.
But this is not inflation per se, it's what's counted as “economic growth”: the median family in 1940 had a much lower standard of living than the one in 2024.
But of course sorting what's inflation and what's relevant economic growth is highly subjective: some things like cars and housing have literally inflated (they are enormous now compared the what they looked like even 40 years ago) and that's usually counted as economic growth, but is it really? In some way it is: having a bigger house is nice. But in other way it's not: do you really need that much space when you're older and the children left long ago? And sometime it's actually a net loss: living 30 kilometers away from work and depending on a car for everything is not a gain.
Same for electronics: computers are much, much faster than they used to be in 2000, so the statistics counts that as economic growth. And it is, you couldn't do modern AI on 2000 hardware, or physics simulations for industry and all. But at the same time, for the average consumer, the gain in speed has been eaten by software consuming more and more resources. Sometimes from sheer laziness (there's literally no reason for Windows to be this slow) but sometimes it's a bit more ambiguous: today's video games couldn't run on hardware from 20 years ago, and I remember being very happy to see the graphics improve during my teenage years so it's not entirely pointless. But at the same time, it's not as if video games were more fun or enjoyable now than they were 20 years ago: the consumer surplus from video games is basically the same no matter the quality of the graphics, so maybe it shouldn't be counted as growth at all.
The measure of “real” economic growth (and the measure of inflation) depends a lot on how you weight these things (it's called “hedonic adjustment”) and as we've seen, it's very difficult, and fundamentally subjective. And I wish statistics agency provided a measure of CPI without hedonic adjustment in addition to regular CPI (like they already do multiple variants of CPI depending on the basket of goods that's taken into account).
