They do most of the chores despite having jobs. We're a very patriarchal society still.
That answers your own question, does it not? That is, fathers don't take time off to spend more time with their babies because they are too poor to risk losing that job?
(This assumes that men tend to be paid more than women.)
That is, if only 10% take time off, and you only know 5 middle-class people who could afford it, then odds are that even at the Dutch level you wouldn't know anyone who does that.
I suppose it's possi ... okay, that was too easy. A search for "how many Dutch fathers parental leave" comes up with http://www.dutchnews.nl/news/archives/2015/06/just-one-in-fo... which says "Just one in four Dutch fathers takes parental leave".
I also read that in some of the European countries (I'm from the US) there is a right to part-time employment while on leave. I figured that mosselman was from one of those countries.
Searching now I found http://cepr.net/documents/publications/parental_2008_09.pdf from 10 years ago which says:
> Of the 21 countries studied here, ten allow parental leave to be taken on a part-time basis: Austria, Belgium, Denmark, Finland, Germany, the Netherlands, Norway, Portugal, Spain, and Sweden. Portugal is notable in that it gives parents an incentive to choose part-time over full-time leave: parents have three months of full-time parental leave or 12 months of part-time leave.
Based on mosselman's followup, my guess was correct.
> Portugal is the member state with the fifth longest period of paternity leave, with a potential of 21 weeks to care for their newborns. However, this report paints a different picture when it comes to the division of domestic chores. Here, Portugal joins Estonia, India, Japan, Mexico, South Korea and Turkey as among the countries where women put in three times more time on such tasks than their male counterparts.
That sounds in Portugal fathers are more expected to work/be a career man, and mothers stay home, than in the Netherlands.
