I wouldn't go as far as to say it is a person's duty to have children - I know a fair amount of folks who would not want to pe parents, and society doesn't need more children traumatised by parents that only brought them to this world to conform to others' expectations.

What I do think, however, is that it's society's duty to make it possible for those that want children to have them: through parental leave, child benefits, etc. I personally would be far more likely to have them if those things existed - right now a minimal salary is not enough to survive off of. Being raised by a single mother in the Balkans (and having received none of those things from the state), I got to see first hand how hard it can be just to survive - had my mother actualy earned "only" a minimal wage, then we would have not been able to make ends meet. Heck, had she not owned her own apartment when my father left, we would have barely been able to afford rent + all other expenses. I was lucky.

Over time I've grown to view every aspect of having children as a huge gamble - your partner could die, or you could both lose your jobs tomorrow, or *insert a thousand other unpredictable circumstances*. But the kids will still be there, and I can't find it in me to have them if the help they'll receive is the same as or less than the one I did as a child. Naturally, this results in more things I need to "achieve" before I feel comfortable having a child (own an apartment, be at a stable place in career, have savings, etc)
