I got one of the prizes the ACS gave to people proposing the ten best inventions of the 20th century with the entry I based on asking my mother and her mother. Mom’s answer had been “the Pill”; Grandma replied “hell NO, pads! Tampons! Baby nappies! God, not having to wash all that any more!” She’d been born in 1913 and died last year, so she wasn’t quite in the period mentioned by the OP but she was close. On the other hand, she always tried to use the washing machine as if it had been a tub. Most often when she complained that “it’s not working”, the poor thing was so overloaded its safeties had triggered.
In her case the biggest changes had been sanitary accoutrements (good) and machinery (not as good as a washerwoman). Things like communication well, she never sat down long enough to really pay attention. Oh, and her own mother had been a washerwoman with a unique business model: instead of going to clients’ houses and doing the washing there as was customary, she picked up the washing, did it at her house and returned it clean and ironed. Now you can’t find washerwomen anywhere in the developed or even semideveloped world; the closest thing is laundromats. Wahing machines are one of the first appliances people get.
For my paternal grandma, who was born in 1908 and died in 1994 and who was in a higher socioeconomic class, the biggest changes included better schooling in general, more women going to college (the fact that her own business school class included women, for the first time in Spain, was a Huge Deal - now women are the majority in business school), machinery (a great invention), communications (movies, radio, tv), more ease of travel… she lived through multiple changes in the situation of women: Second Republic, Franco’s dictatorship, then Democracy-Again. And unlike my maternal grandma she was very conscious of each of those changes.
Both of them lived through The Hunger Years, first of the Civil War, then the combination of our post-war with the War in Europe, then the isolation years. Both remembered the lunar landing with wonder. Abuelita (paternal) was very much a believer, both in God and in Man: she expected to see many more wonders, including for example “an end to hunger” (her own mention), albeit most of them from Heaven if she made it (which she hoped she would but “it’s like a test in school: you do your best, but you can’t be sure it’s been good enough until they give you the grade”). Yaya (maternal) was a very negative person and never seemed to think very much about the world more than a few yards away; anything for which she could see a direct effect on her was considered, anything for which she did not see a direct effect was discarded from consideration. If you’d asked her about hunger in the world she would have said to shut up and aren’t you going to finish that.
So, two women of similar age, living in the same country and for several years in the same town, but who had very different outlooks. Their differences in their lives weren’t so much of circumstances as of what they themselves made of those circumstances.
