Similarly there where a great deal of households in the 1940’a with two working adults.

I'm guessing the rise of dual income houses is much more visible in the median than are retirees dropping down the labor force participation rate.
Married-couple households however have dropped dramatically over time, 76% of households in 1940, 55% of all U.S. households in 1990, and 46% in 2020. “In 1940, married couples with children represented 43 percent of all households; married couples without children represented 33 percent of households”
I cannot find stats going back, but a majority of current households today are dual income. https://www.bls.gov/opub/mlr/2020/article/comparing-characte...
This effect of the median family being dual income is likely true for now, and false for 1940. It is much stronger if you subset down to "families", but this nuance doesn't likely appear in the "median household income".
In the 1940’s multi generational households with multiple income earners were common. In 1940 only 7.8% of all households had a single person vs 26.7% by 2010. Working adult children would frequently stay at home until marriage and sometimes past that point.
This is one of those things you need actual data based on similar definitions to compare.
The USA in 1940 were a smaller empire than they are now so, I might be wrong, but the Manhattan project money came mostly from inside the country.
This means that it's easier for Apple to find and spend those money than it was for the USA in 1940.
Most people don't actually seem to want to have mist most of their waking hours free to do whatever they want.
Personally I work part time on software projects and have a small farm/homestead. I usually don't know what day of the week it is and have the freedom to take each morning yo decide how I want to spend my day. I wish everyone could experience that freedom, even if they find they don't like it.
It's utterly ridiculous how much of the productivity increases of the last decades ended up not distributed to the workers either in terms of wage/salary hikes or reduced working hours. Something like billionaires rarely existed for a long time, usually it was the royal family and that's it - and now, alone in the last 20 years the amount of billionaires is 6x higher than at the start of the millennium. All of that wealth has been looted from the lower classes and in quite a few cases the taxpayers.
