> Most things people eat need hours of preparation that isn't counted in you 15-20 hours for example.
Yeah, and we now expect women to work 40+ hour work weeks and house work on top of that. That is the thing causing societal reproduction rates to plummet.
Let's just do the math: a day has 24 hours. The recommendation for healthy sleep is 8 hours. Then, you work for 8 hours, with 1 hour added for the unpaid lunch break. That's the two largest blocks, leaving 7 hours to distribute... dedicate 3 hours for the "staying alive" stuff (preparing for going to work in the morning, aka breakfast, shave, getting dressed, preparing dinner, eating dinner, have a shower and at least some unwind time to fall asleep).
And that in turn leaves only 4 hours for everything else: running errands (aka shopping, dealing with bureaucracy, disposing of trash, cleaning), just doing nothing to wind down your mind from a hard day at work, hobbies, social activities (talking with your friends and family or occasionally going out) and, guess what, actually having sex.
Easy to see how that's already a fully packed day. Society just took the productivity gains from women no longer having to deal with a lot of menial work (washing dishes and clothing, as that got replaced by machines, and repairing clothes) and redistributed these hours to capitalism.
And now, imagine a child on top of that. Add at least half an hour in the morning to help get the kid ready for school, an hour to drive the kid to errands (because public transit is more like "transhit"), and another two hours to help the kid with homework because that workload is ridiculous and you don't want the kid to fall behind kids of parents rich enough to afford private tutors. But... whoops, isn't that just about the entire "everything else" time block? And younger children need even more work, constantly changing nappies, going to the doctor's all the time because it's one new bug every new week and sometimes the bug also catches you cold...
