Genuine question but definitely most interested if possible in actual data not anecdotal. On most threads about SAHMs people will always say that women have always worked apart from the rare recent middle classes who are an outlier.
Is that true? For example I was reading Call the Midwife; none of the women seem to have a job despite being very working class. Reading old books I never read about married women with kids from any background who worked.
In my family I don't know of any married women who worked but fair enough, they were generally wellish off.
All that is anecdotal though!
If women did work, who looked after their kids? I honestly don't see how it would be possible for most women with children.
