> why school is considered not discretionary time?
Because most schools are so underfunded that, in practice, they are prisons with a food quality to match instead of providers of an environment conductive to good learning outcomes. State obviously varies by country a bit, but it's painfully obvious that schools (and their precursors daycare and kindergarten) primarily serve to enable women to join the workforce.
