They've continued trending down since then, especially when you count hours of domestic labour, which has dropped a lot (and no surprise, since you're not getting paid wages for those hours generally.)
This, I think, leaves out how much formerly domestic labor has been converted into social labor provided either by the state or market forces. Which could be responsible for a lot of reduction as well, as when one does this efficiencies of scale and rationalization can take place in an organization. I have no idea how or why either aspect would be bigger. Hypothetically, reduction of (for example) childcare hours could be as much about proliferation of daycares and kindergarten and schooling in general as it's about development in domestic childcare technologies. Eating and fix prison is microwaves and McDonald's, etc.
But what I'm saying is that both paid labour and unpaid labour (or "domestic labour") are both going down in number of hours. People working in daycares and kindergartens are already counted in the paid labour hours. What technology does is make domestic labour time-effective enough so that keeping house is no longer a full-time occupation, which permits for the expansion of other kinds of work.

How can you claim this when essentially they have doubled - two wages are (usually) needed to provide for a family these days.
So don't family. Problem solved :)
Seems like a reasonable solution for the whole world to adopt. What could go wrong?
