One really common that myth this article busts is about child care.
"Child care is virtually free in Vienna and extremely expensive in Zurich, but the Austrians and the Swiss have the same fertility rate."
I don’t think the evidence either way is strong enough to call that one a myth. There are lots of other differences between the two countries that could offset the impact of Austria’s childcare subsidies.
There are plenty of longitudinal studies from various geographies, which I would summarize as “childcare subsidies increase birth rates in some contexts, but the effects are complex and depend on program specifics.” E.g. https://pmc.ncbi.nlm.nih.gov/articles/PMC2917182/ and https://clef.uwaterloo.ca/wp-content/uploads/2024/09/CLEF-07...
Just to expand a bit on Zurich and comparing with Slovenia (another "very socialist" country).
Childcare in/around Zurich is (was 2 years ago) 2500 - 3000 CHF / month (lower prices after ~18 months). This is and isn't expensive. The list prices are high, but so are salaries (and taxes are low), and this is cheaper than rent (for 1 kid). Not subsidized.
In Slovenia, the full price is about 700 EUR / month, subsidised up to 77% by the government (i.e. by high-earners, effectively a double-progressive taxation with already high taxes).
What you get for that price in Zurich? A lot! Kindergarten starts at 3 months and can take care of kids for the whole work day (7am-18pm). Groups are tiny and lots of teachers - 3 adults per 12 kids. Groups are mixed age as well, which I think are preferable. You also get a lot of flexibility - e.g. half-days (cheaper) or only specific days per week (e.g. Mon-Thu). Jobs are equally adaptable, a lot of people work 80% (so Friday free, spend with kid(s)).
In Slovenia, the situation is much worse. 2 teachers per 12 or even 20 kids (after age 4), age-stratified groups, childcare finishes at 5pm (but start at 6am, if someone needs that...). Children are only welcome after 11 months of age. No flexibility at all. This is all for public childcare - we also looked at private, but generally you pay more (1000+ EUR) but get ... not much more. Maybe nicer building (not even), but groups are equally large (IMO biggest drawback).
So as far as childcare is concerned, Switzerland is IMO much better.
But where Switzerland fucks you, is elsewhere. As mentioned, tax is low, so that's a plus. But there's minimal maternity leave (hence kindergarten starts at 3 months). If women can, they take more time off work, but not everyone can. What I wrote above about "kindergarten" only applies until 4 years of age, after which "preschool" starts, which is government-funded and hence free. Well, "free". It ends at 12pm after which you need to move your kid back into private childcare if you have a job. After that, school starts, which has a lunch break around 12pm as well - children are supposed to eat lunch at home - which again isn't really compatible with 2 working parents.
I'm not in Switzerland any more so I don't know how people actually manage when kids start school...
I can only speak for myself, but 2 was a good number for me. This amounts to somewhat less than a replacement rate. My wife and I had enough time and energy to give the kids what they needed, and still have some for ourselves at the end of the day. And if either of the kids needed extra resources or attention, we were able to do it without neglecting the other one.
I am not worried about a population decline, to be honest. Even disregarding AI, improvements in technology and food production mean we can leverage resources in a way that would seem like magic to the people alive when my grandparents were born. I would rather take care of the people we have in this world - the whole world, not just my country - than see more people born into slums and poverty.
Even if there is a cliff, I don't think it's an existential crisis. I say without irony, I believe the market will adjust. Wages will go up in jobs that are needed, and workers will have more leverage and more mobility, socially and geographically. It's hard for me to see that as a bad thing.
Even if you believe that technology will let us keep pushing the earth's carrying capacity indefinitely, to what end? It doesn't seem like anyone has a real plan for expanding beyond 8 billion that isn't just a promise that we'll figure it out when we get there. We aren't taking care of the people we have now. Never mind the ones yet to be born.
I don't want to live in Brave New World and I also don't want to live in The Dosadi Experiment. And I don't want to condemn the future people to live like that either. I know those are works of fiction, but both seem plausible (in the general sense) at this point.
(Edit: not Brave New World. I am thinking about a story where people lived in dense arcologies with tight surveillance and social control surrounded by robotic farms. Sorry I can't remember.)
Childcare can be nice to have but it can also be a full-time job just getting the kids there if you have more than a few.
We certainly take advantage of things like free preschool; but if we look at it objectively (and ignore benefits to the child) it consumes more time than if we didn't use it - getting him ready, walking him to school, picking him up, etc. Since it's free, we look at "time spent" and it's something like 2-3 hours spent to "get" 3 hours.
