If that would be the intent, arcade cabinets, open play fields, parks and other social areas within school grounds would be the way to go.
My understanding is that the current school "format" was developed during the industrial revolution stage, and its meant to instill into kids that schedule and "lifestyle". Which to many extents hasn't kept up with the way society is evolving.
More funding into schools would help (which countries contribute significantly to education anyway?), but also by helping kids develop and learn in what they have an interest. Instead of the currently standardized boring circula. And the sometimes insane hours.
On that note, during highschool I had days where I've had up to 7 different classes a day. At least when you go to work, even if it's 8 hours, I (and maybe you as well) got to slack at least 1 hour a day in the morning, or even in the afternoon after the 1 hour lunch break.
