That doesn't really fit my experience. Both my parents were working hard hours when I was in highschool and my participation in after-school sports meant that I was occupied until they finished out their work day (which ends in the evening, contrasting with the schoolday which ended in the early afternoon.) Practice before school was convenient for the same reason; my dad had to leave for work at 4:30am, and my practice started at 5am, so that worked out well.
