In 1924, it was 40 hours per household. Most workers had a wife to cook, clean, and raise the children. It should still be 40 hours per household. Women, men, and enbies should all work 20 hours a week. Anything more than that should have legally mandated overtime.
Maybe if we did that, the zoomers could actually afford to get married and have kids.
That one's biased. It doesn't consider reproductive labour to be labour, which is a social bias rooted in historical misogyny that devalued "women's work".
And even then, it should have had a spike anyway during the feminist revolution, when half the population stopped working "0" hours. It doesn't count women who didn't work. It only counts people currently in the workforce. It hides the fact that's twice as many these days.
