I disagree. I'm from Slovenia, and in this culture both parents have been working parents for generations (i.e. both my parents and all 4 of my grandparents were working). Marriage still makes a lot of sense, simply because (1) people like companionship, (2) it's easier if you share domestic tasks, and (3) you need 2 people to make a baby. Probably other reasons as well, but these are the most basic ones, I think.
