I don’t know if it’s induced demand, revealed preference or Jevon’s paradox, maybe all 3.

So it's only men who got relief?

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.

OK, but I doubt we're washing 10 times as much clothes, unless are people wearing them for one hour between washes...

(Quotes because I personally have a significantly harder time doing bloody housework...)

> 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!

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.
