The picture was quite different in Denmark, where I live, to the one you are describing.
From the early 1970s practically no women stayed at home looking after their children.
The attitude here was that once the fortnight's maternity leave was over, you had the child looked after during your working hours in a state-run crèche with fully qualified staff.
Not because this was necessarily better for the baby, but because no self-repecting woman who was fit to work wanted her husband to have to support her at any time during her adult life.
Equality between the sexes was seen as being achievable only if women trained to do a job after leaving school and earned their own living thereafter, contributing to their own pension fund, and to society through their income tax.
Those were the years were women campaigned for the same wages for women and for men, doing the same jobs, for working our way up to leading positions in business, the academic world, in medicine, and in the Protestant churches.
Most women too wanted to know that they could support themselves and their children if widowed early, and know that if the marriage proved a disaster that they could afford to get a divorce.
On a less elevated plane, it was also a financial neccesity for women to work, as even in the 1970's one income was not enough to enable you to both buy a house and afford to live in it.
That has not changed since then, although it is rare today for men and women doing the same job not to be paid the same, and maternity leave is now a full calendar year for the woman and six weeks or so for the father of the child, irrespective of whether the parents are married or not.
Unemployment for the last 20 years has been an ever present threat, making women very dubious about availing themselves of part-time work while their children are young, if they do have a job.
Some of the unemployed young mothers prefer to try and do without unemployment benefit or social security (two different things here) in order to bring their children up themselves and save the crèche and kindergarten fees. However, this is only really possible finacially, if either their husbands earn very well indeed, the couple have no student loans they are paying off, which is very unlikely, or they live either in the country or a suburb with a garden large enough to grow their own fruit and vegetables, keep hens and in other ways be self-sufficient.
