For countries who have tried this it is very popular and it has been considered a success.
Parents really like it.
It is not just “mild uneasiness” For many countries it has significant career repercussions to prioritize family. I know many Nordics who while living in the US who experience that they are not taken serious by their boss if they priority family.
You can even find plenty of Americans living in Nordics who can attest to this. If you prioritize family you are considered as not taking your career serious.
I mean American bosses freak out when people are away for more than 1-2 weeks.
