(poor Alma! she must have loved living over a laundromat after that)
Good point.
People who said they'd come from rural and/or poverty backgrounds would remark that they remembered doing work like that but they didn't seem to be particularly nostalgic about it. However, middle- or upper-class people, and most people from cities, tended to over-romanticize all that. I did enjoy hearth cooking and the exercise I got, but I wasn't really living a pre-industrial lifestyle; I did it from 8:30 to 5:00 five days a week and went home to all my modern conveniences. But it gave me enough of a taste of that life to know that it wasn't "quaint" or fun; nor were the people necessarily more "real", all of which are illusions that people who never had to do that kind of work indulged in.
Totally agree. People tend to romanticize the past as well as the lifestyles of "simpler," less high-tech societies as being more authentic. For example -- and I apologize, as I know this isn't really your area of interest, but it's such a great example -- they'll talk about how wonderful "natural" childbirth is, free of all those artificial modern interventions. And while yes, you can make an argument that we've gone too far with modern interventions if people are scheduling their C-sections to accommodate their vacations or something, but let's not romanticize an era when babies were delivered with a minimum of medical frou-frou, and an alarming number of mothers and babies did not survive the event.
I think baking a cake from scratch is a fine way to spend your time if you really like doing it, if you like to bake the way other people like to read or watch TV or garden or do pottery or craft handmade furniture. My aunt is this way: she truly loves to bake and cook, even though she doesn't always eat the stuff herself. But I think expecting everybody (i.e., women) to do more scratch cooking all the time, regardless of personal interest, because it's "healthier" or otherwise morally superior can manifest as a perhaps unwitting yet insidious pressure to get women to focus on domestic chores at the expense of other achievements. There's only so much time, and our great-grandmothers not only didn't have convenience products, they also didn't have the internet or cable TV or movies or much reading material or 40-hour-a-week office jobs.
In practice, luckily, most people can make the choices that most suit them -- they love to bake cakes from scratch, but they wouldn't dream of pinning their laundry to a clothes line, let alone making their own soap from lye. Or they make the soap but buy the cake from the bakery.
If I'm going to bake a pie, it's going to be from scratch: I make the crust from flour and stuff, use fresh fruit or, my specialty, sweet potatoes, for the filling. But I only do it once or twice a year, not for every big Sunday after-church dinner.
