As said elsewhere - the younger generation gets out by going online. Bad for both their physical and mental health. They also work too hard as we've created rough expectations and requirements. My high school daughters average more homework daily than I did weekly on all but my worst weeks (1 or 2 over 4 years). While class selection impacts this some, it does not appear atypical.
Many in my generation have been overly protective or helicopter parents. What did we expect would happen?
