So maths time…
If that cart is a weeks of groceries, it takes 1250 weeks of groceries to buy a house in 1980.
According to a 2024 USA today article the average family with kids spends $331 per week on groceries.
If the groceries per house ratio stayed the same, a house would be $413,750 in 2024.
The U.S. median home price was $412,000 in September 2023, according to Redfin.
I dunno seems pretty proportionate.
That’s not the issue.
Average annual household income in the US in 1980 was $20,020- 42% of a house (average cost of a house in the US in 1980 was actually $47K).

Average annual household income in the US in 2022 was $74,580- or 18% of a $412K house.

And “household income” definition also changed: at the time the most common was that only the man of the household was working. So I’d say we are down to a quarter of what was earned then.
