I mean, it's a wonder women still choose to have children. I see it is a triumph of the human spirit, because through a purely capitalist and individualist lenses having children doesn't make much sense.
Does not make much sense for a woman. Until recently, with the advent of a relatively safe society and without birth control options, they basically had no say in having children.
Now, we get to find out the market price (excluding long term externalities) of birthing a child (and child #2, 3, 4, 5, etc) without the fact of being physically weaker tilting the scales.
