That only depends on how you measure value.
A parent leaves their kids with their grandparents during the day = $0 GDP.
A parent drops of them off at daycare = +$X GDP.
Just because people were not working in the economic system does not mean there was not real value creation.
My mother sometimes worked, sometimes did not. The difference in the quality of our lives was quite noticeably more negative when she worked. That 'negative value' is not measured in the GDP - only the 'positive value' of her income.
I'm not saying that she shouldn't have, and certainly not that there should not have been mass reforms - but it's important to remember that much of 'real consumer surplus' is simply not measured in the GDP.
Policies that focus on the GDP tend to overweight measurable economic activity - while other elements are externalized and suffer.
The environment, community, social cohesion - they all have value to us but because we don't put numbers behind them, they don't fit into the equations very well.
