1936
You all may be missing the point, in 1936 (Great Depression) unemployment was at 16.9%. So $ 1,600 annually was an average thats if you had a job at all that paid an average, many men worked odd jobs where ever they could find them, and did NOT get paid an "average"
If you where a women, you might find yourself with a bigger problem, in so much as employers didn't have to pay the same wages for the same job or same kind of work!
My Grandmother was a divorced women with two kids in 1936, and had to lie to her employers by telling them that she had never been married, and of course didn't have any children! Had they known, they would have looked down the end of their noses at her (a divorcee) and told her to go home, and back to her husband! Thats was just the reality of those times! Even WITH her job she would have been hard pressed to find a store that would have extened credit to a "mere" women, without a reference (a man) and if she had managed to get one, it would have been ONLY with THAT store, not to be used anywhere, like a VisaCard
In the movie "Now Voyager" remember the story was about a wealthy family holding a high position in Boston in the 1940s, not the average "working" class in the mid 30s.
Also many people of the time did not believe in credit, or "buying on time" as they used to say, and were frightened by owing money that they might find (in unsure times) that they couldn't pay back later. This was the time of "bread lines" and "soup kitchens" and a popular song called "Brother can you spare a dime"
So back to washing machines. if you look at the statistics and polling of 1936, you will find that it was common that many households simply did not have one! They made do with what they had! A washboard and the kitchen sink or bathtub.
By 1960 the polling shows that 1/3 of the households still did not have washing machines, and that those that did, almost half were still wringers that had been purchased 5 to 10 years earlier. and since they were still working " why buy another" Another % in 1960 were still buying wringer types because they could get them cheaper, or second hand, as the wringer models were less likely to break down, and could easily be refurbished.
