I also think the amount of overshoot is proportional to the amount of sexism that was present in a society thirty years ago. I believe Northern Europe has been trending slowly towards gender equality since the 90s, and thus the amount of overshoot here is much less from the recent rapid changes like #meetoo.
Also our kids roam around the neighbourhood freely. We're thinking of giving our 9-year-old a cellphone soon, for now she just has an analog watch and we agree on what time she has to be home by.
If you look at statistics, the rate of women murdered per capita, and the rate of women who experience sexualized violence per capita, are around 5x higher in the US than in Northern Europe. The murder rate here for children (excluding by their own parents) is below 1 per million children per year.
We're definitely not perfect, we have a long way to go still, but we are starting from a more equal place if you look at the status pre-2017.
