Ah. Well, historically, men were always free to have mistresses and beat their wives, so it's better that they cut each other loose rather than play those games. I don't think children are considered more disposable now. I know a lot of older people whose siblings were dumped with a different family and they never saw them again. My grandpa's brother got dumped at some point (in the '30s), given to relatives who treated him like trash because he wasn't their biological kid, but they eventually took him back, unlike some families. And kids are treated SO much better now. At any rate, I dispute the idea that people are worse now, to animals or humans. There's a fair amount of evidence to the contrary.
