text: a school day shouldnt be extended because kids need play time and relax time which they would not have if they go to school 2more hours...between home-work,chores,15 minutes of reading and a bed time that is probably fairly early when would a child have personal time?...got to fit dinner in there too...unless they go later to school...by the way also if the parents work and the kids get out late the parents may be less likely to be helpful with home-work and such because they will be tired too
