The US is not Sweden. In the US, you die or your kids starve if you don’t have enough money. So when you see a statistic that women have the altitude to go into a high paying career disproportionately to their actual representation, it’s harder to dismiss that just by saying “oh they must prefer to do something else.”
Beyond that, I’m not inclined to believe that Sweden really is more gender equal. It seems based on little more than assumption.
