40 hour workweek is excessive. This is based around units containing at least two adults, maybe multigenerational homes with grandparents doing childcare. Now that we expect dual incomes the workweek should be 20 hours at most before overtime kicks in.
What I am getting at is that just giving people time back to exist could happen with changes to the current system. Unfortunately that means smaller yachts for the people on top, so we cannot have it.
