women increasingly went out to work to keep the whole enterprise float. Soon millions of people were caught in a spiral in which they worked harder and harder to buy labour-saving devices that they wouldn’t have needed if they had not been working so hard in the first place.
Tosh.
Women went out/back to work because many of them actually enjoyed their jobs and responsibility during the war years, plus the independence and satisfaction, not to mention the money, they earned. Plus the chance to use their brains and education.
And as for buying labour saving devices, who wouldn't prefer to have a fridge rather than a meat safe and a cold slab in the pantry, a twin tub rather than a washing machine dragged across the yard and an antiquated mangle, a dishwasher rather than washing every pot and pan by hand. Time saved, and freedom from spending the day as a skivvy.
All the above applied to my mother; she said there were far too many people who seemed to think a woman was born with a dish mop in one hand and a dustpan in the other.
