People who choose to have kids tend to lean very practical and no-nonsense relative to those of us who don’t. They don’t process in this angsty way. In fact they tend to get religious/philosophical if they *can’t* have kids for some reason like medical issues
It’s just about defaults. It’s only when you go against societal defaults through choice or constraint that angst appears and you philosophize. Going with the defaults willingly doesn’t cause angst or trigger much reflection.
