I think it is actually a lot worse than household incomes suggest. Having a parent stay home is tremendously valuable to a household in providing childcare, food preparation and all sorts of other valuable labour. None of this gets measured in incomes/GDP but as soon as you have both parents working and paying for childcare, paying for prepared meals and so on it does get measured in household income and GDP. So when we just look at household income we're actually underestimating the decline because there also used to be more unmeasured value provided by stay at home parents.
