Washing machines created a revolution where we could now expend 1/10th of the human labour to wash the same amount of clothes as before. We now have more than 10 times as much clothes to wash.
I don’t know if it’s induced demand, revealed preference or Jevon’s paradox, maybe all 3.
I've done some 3rd world travel without washing machines for a while and my laundry was once a week dunk stuff in the sink for 5 minutes with shampoo + rinse water, wring and hang up. I don't buy the whole day being necessary thing.
Well, now we can own more clothes! And we can wash them more often! And rather than specialist washerwomen, everyone can/must use the laundry-room robots!
Before teaching your children to do chores: x hours per week for chores
After teaching your children to do chores: y hours per weeks to have annoying discussions with the child, and X hours per week cautioning the children to do the chores, and ensuring that your children do the chore properly. Here X > x.
Additional time for you: -((X-x)+y), where X>x and additionally y > 0.
I imagine standards have also shifted. It just wouldn’t have been possible to wash a child’s clothes after one wear before the invention of the washing machine. People also had far less clothing that they could have even needed to wash.
John Maynard Keynes (1930) - Economic Possibilities for our Grandchildren
> For many ages to come the old Adam will be so strong in us that everybody will need to do some work if he is to be contented. We shall do more things for ourselves than is usual with the rich to-day, only too glad to have small duties and tasks and routines. But beyond this, we shall endeavour to spread the bread thin on the butter-to make what work there is still to be done to be as widely shared as possible. Three-hour shifts or a fifteen-hour week may put off the problem for a great while. For three hours a day is quite enough to satisfy the old Adam in most of us!
