Conversely - it'd be interesting to investigate whether other statistics have improved over the past decade with parents being increasingly responsible for their kids after school - reduced shoplifting, reduced graffiti, reduced smoking/drug use, reduced teen pregnancy, etc. Its quite possible that increased organized sports and after school activities (particularly robotics, math, computer science) could actually improve the capabilities of society as compared to just leaving the kids unattended after school.
