Well, capitalist society, not technological. Capitalism hates investing in children but loves exploiting them (see Jeffrey Epstein, many of whose victims came from poorer families in Florida). But most decent people want to invest in their children, the result being those who can afford it delaying our foregoing birthing altogether, leaving only a few classes of people birthing regularly (the rich, the too poor/uneducated to reduce/avoid birthing, those who resign themselves to accept/expect worse lives for their children, those who don’t care, etc.).
