"But it doesn't discount the fact that it's easier to start a family for someone with a stable job with a support network."

Definitely. Still, sometimes you have to take risks, as you are not getting younger. Maybe moving again somewhere, where you could have a support network, even though pay is lower, might be an option?

We had grandparents around, that definitely helped. No idea, what other people do without that. If both parents get sick, the child still needs lots of care .. and you don't want some stranger to take care of your baby.
