I wonder how much the isolation and financial burden of modern American life plays into this. The usual narrative is that in the past, not only were a couple's parents involved in raising the kids, the couple also had a much stronger involvement in the community, so members were able to help each other out. But in the quest for home ownership and rampant consumerism, we've lost that sense of community, and raising children has become a burden since we're all living to work.
