Sounds like the who age verification debate will just solve itself. Just wait until there aren't any more children and then we don't need to worry about protecting them.
You jest, but I'd think it really is the opposite. Hard to care too much for a child if you've got five spare ones.
Do you have children? Because I've never heard a parent think that way
I think it's a little brash, but I do think that if we could accurately measure "care" that people with 1 child care statistically slightly more for them than those with 5 might care about any individual one. Not that they don't care, but that the one with 1 would worry more. Like how families with 1 daughter and multiple boys might dot on the only daughter a bit more.
I mean historically this is exactly how it worked. When infant mortality was 25-50%, people often had 10 children or so. Maybe 5 would make it to be adults, but people back then didn't view death like we view it now. Sure, they mourned, but losing a child was not a "stop the world" event, because you could expect to lose many. So, it couldn't be.
That was a little over 100 years go. So, a long time, but not that long.
