It's also completely against human nature, especially when it comes to raising kids. We have always lived in large groups and kids were nurtured by and brought up by many members of family, instead of just father and mother. It results in much healthier humans, who learned from all members of family, because who's to say that father and mother themselves only are best guardians? Not to mention the sheer amount of effort required to take care of a child, which was shared by much larger extended family or just tribe members. Today's nuclear family mostly brings mental issues and overburdens the parents in an unnatural way.
