I'll add religion to the mix. We're less religious now. Even folks who are religious now(at least in the Christian West) seem to practice a different religion than we did 50 years ago. Religion does many things, good and bad, but it definitely prizes children and reproduction. If it didn't, it would quickly get replaced by a mode of thought/belief which did. I'm not advocating for religion here, just stating that it likely plays a large role in reproduction.
