@muyuu So you're essentially saying that because women have to negotiate more "off-time" than men, they'd either be incentivized to not have any children at all, which would result in the human species to become extinct, or they are disadvantaged, as I said in my OP. "And it has been so for centuries", this is the patriarchy that many "progressives" want to get away from.
That premise is completely false from the start. Women don't raise children alone and haven't done so for centuries. Family is the foundation of society. It doesn't cost her more than her partner, who's equally as liable for family expenses as her (usually more).
Taking care of the disadvantaged is a whole different story. We are talking about socialising child care here, or not, which is not an emergency/exceptional issue.
Humans, if anything, have too much natural drive to procreate until they deplete their available resources. They don't need any incentives, quite to the contrary.
