A couple folks thought this post was "blaming women for the problem." No. First, I don't even think low birth rates are a bad thing. Second, the long-term decline in birth rates originates from two GOOD things: women's labour force participation, and women gaining bodily autonomy over reproduction.
I'm not sure I entirely buy this. Are costs - esp housing - mitigating the growth of families? Probably! But how significant is it relative to other factors (particularly women prioritizing careers)? This is an empirical question that remains too understudied to make definitive claims about. 1/2
