This report from UCLA hit home. For a time, our family struggled with family balance, and it's only in the last few years, we found the right answers for our situation. The changing sociology of dual career families does affect learning- and in profound ways.
The takehome points for this study is that children these days have much less time for face-to-face interactions and conversations with family members, and less opportunity for idleness and daydreaming. This is not good. All of these activities affect the development of character, social interaction, encouragement, and creative vision. In the histories of famous people, families often figure prominently as sources of inspiration and encouragement. We need to figure out how to allow more thoughtful and intelligent parents flexible working hours and working options, so they can spend more time with their families.
