> Disability, illness, a layoff

I've faced all these (disability from a young age even) and as a result, I don't think there's any way I could raise children. Both because of my own issues make it seem challenging beyond possibility, but also because I wouldn't want to force a child to face the same problems I did. I very much believe to each their own on this particular subject, but if global fertility is "collapsing", then it seems like more people are coming to the same conclusion for one reason or another.
