This part ain't correct, if you actually traveled properly in such places you would find much better community/family support for raising kids compared to typical western young couple situation. I ain't saying every single young family is better off like this, but on average the difference is often staggering.
What I mean - for us, both having high intensity jobs that required 17+ years of hard studies and moving across various parts of Europe, going from couple/married but without children into having 2 small kids a massive shock in every single aspect of life since we raise them largely on our own, families are very far. Families in such places face on average significantly less shock in such situation, mostly they continue in their lives as before (the guy) and women take care of kids for some time as is expected. Of course this is slowly changing into that western model as people get better white collar jobs in big cities.
