DST works by tricking people to wake up and get to their daily activities an hour earlier than they normally would. And it is sold as "giving" people an hour extra in the evening. They could do that without changing their clocks by just waking up at 5 instead of 6 and working 7-4 instead of 8-5, but most people don't want to wake up earlier. So we use DST to trick them into doing it.
Doing DST as a whole society also helps for people who don't have flexible hours for their daytime activities.
But i realized a while ago that the twice a year time change is the PRIMARY reason why DST even works. Because without the constant change, people would just adapt to the new timezone. Daily activities (like school and work) would shift to starting an hour later. Lunch would start being eaten from 1-2 instead of 12-1, as the new time would be when the sun is at its highest. Dinner would be 6-7 instead of 5-6, because that is closer to when the sun is setting. It would take several years, but eventually, society would shift its schedule to closer match the sun. And the way that DST "tricks" people into getting up an hour earlier would stop.
btw, your preference (and mine) for year standard time is the way most of the world works. Gray countries in that map do not do DST. It's really only US, Canada, Europe and a few other places. And I'll never understand DST in Alaska, which is already entirely in the wrong time zone.
