Every support system, from the "family home" where the grandparents have a bed, to the woman not working and taking care of the kids, has been systematically destroyed. Now everyone is expected to work and live alone/as a couple, and they have basically no physical support for raising a child.
I think this is the main issue right here. The others being increased housing cost (you need space for kids) and increasing costs (daycare, kindergarten, nappies etc.).
