I don't know if it's based on culture or laws, but this article doesn't really ring true to me as a Swede. My father, like many (probably not most though) fathers I know, spent as much time home with the children as the mothers did. As I intend to as well when the time comes. It is very possible for both parents to keep up their professional careers if the burden is split between them, I think.
From what I recall, Sweden has very different cultural and legal norms around male parenting than the rest of the world - for instance, their paternity leave laws are much more friendly to fathers who want to stay at home and look after the baby so the mum can return to work than in most other countries.
