Gotta keep the evening lighter, especially now more people aren't traveling early mornings as much - which I always found a weird argument, not like you need the sunlight to be able to get somewhere. Most people (I would bet) want to finish work and be able to do things after.
At my latitude (northern part of the US), the changing clock doesn't affect that. It only affects whether they'll be traveling in the dark in the morning or evening. And, during the depths of winter, they'll be traveling in the dark both ways in any case.
As someone who grew up in Michigan the "both ways" claim seemed odd and upon checking unless "nothern part of the US" includes Alaska/the arctic circle (which seems a bit unfair) that doesn't seem true.
The shortest day for the absolute northernmost point in the continental US has sunrise just before 8:00 am and sunset just after 4:30 pm. With most schools starting at 7:30 and ending at 2:30 it works out for one way adjustment or not. I remember trying to get kids in extracurriculars heading home by sunset was actually a goal of scheduling but obviously that's not always possible particularly during in season due to the extra travel time prior to the game.
