I’d argue that most of those support and incentives are barely enough in modern societies.

In modern societies families are atomic. Parents don’t get support from grandparents very often and sometimes they don’t get any support. There is no community support either, or very very little unless you happen to belong in some ethnics. On the other hand, people are more aware these days and regulations are tougher, so you can’t do a lot of things back in the day, like my parents used to leave 4 years old me to my neighbours for work.

So I’d argue that our society is actually more and more difficult for parents to give birth to babies, especially middle class parents because they don’t even enjoy much of financial support anyway — those goes to poorer families.

And this becomes clearer if you look at wealth distribution. Nowadays, in my city, which is considered as the most affordable metropolitan in Canada, it is very difficult for working people to buy properties with median salaries — and rent has gone up too so you can’t say “just rent it”.

All in all, I don’t know about Northern EU but it is harder and harder for working parents in Canada to have babies.
