I try to reserve judgement, mainly because I never wanted kids, so not having them was an easy choice for me. I can’t pretend to understand the biological drive to procreate, since I don’t feel it.
But yeah…I suspect a LOT of people who have kids (especially young kids) are very much burying their heads in the sand to avoid the reality. Especially as climate-related disasters start happening with increasing frequency. The horror of seeing collapse coming for their children will be devastating mentally - most people will lean hard into the cognitive dissonance to avoid facing it.
I watch them too. And there’s another similar channel of a single young (American, I think?) woman who’s doing the same thing. And again, the locals are very welcoming - I suspect this depends on whether the newcomers are making an effort to integrate, learn the language, etc.
