alt Hacker NewsOne of my hobbies is looking up old prices in the BLS CPI calculator to see what they would cost today (March 2026 is the latest data.)
The June 1940 photograph along Hwy 1 in Maryland had $0.05 hotdogs ($1.17) and $0.10 burgers ($2.34).
The Feb 1959 photograph from the NYC diner advertises a $0.45 burger ($5.14) and probably a $0.75 steak sandwich ($8.57)

One neat inflation calculation I stumbled on is that inflation since 1945 to today is ~20x, so, from the film-noir era to today,
5¢ = $1
25¢ = $5
$1 = $20
$5 = $100
These prices adjusted for today's value seem off though. I'm guessing you'd be hard pressed to find a diner burger for $5.14 anywhere. No, fast food joints are not the same here and not part of this discussion.
Where is the discrepancy? I've never really trusted these "adjusted for inflation" type numbers. I'm not an economist so I have no idea how they are calculated, but they've always just felt off to me. Usually, the numbers are for something esoteric to me, but these are about something I have some familiarity. In my experience, the adjusted burger price is about half the actual cost of today.
I wonder if portion size is comparable.
We may have inflation in more than one sense: prices have gone up, and perhaps the size of burgers and hot dogs have also increased.
No doubt I can find portion size clues if I look around. Haven't done so yet.
