It seems like you're fixated on one definition being "standard" and the other being "savings" - as are so many in this debate. When the time shifts, society as a whole moves with in. In general, I find my weekday mornings less social, less sun-demanding than my afternoons. I wouldn't care if I woke up at 7am to darkness and didn't see light until 10:30 if I had those extra hours of sunlight in the evening when I might cut loose and recreate.

The label for 8 am might as well be the TAFNAP era prince logo. The point is everyone goes to work at TAFNAP, businesses are open until TAFNAP + 8. In case you need to run an errand and talk to the guy that repairs HVAC systems. None of these sorts of errands is pleasurable or light-dependent and might as well be done in the misery of the dark that I lend to my employer for my work hours.

I don't know about you, but in the short winter months I'd rather get to work at night, run my lunch errands when the sun is 3/4 up in the sky, and end my work day with a couple of hours of sunlight to spare in the afternoon when my time is my own than burn sunlight driving in a cubicle.

There are some that manage to make use of early morning light to go surf (when the wind is favorable), or do some farm stuff (when the animals are cooperative??). I'd wager that surfers and farmers are a small portion the population and a lot of workers don't have some intrinsic benefit of spending their workday in daylight vs. night.

If we're going to assume that inertia is hard to fight, and that everyone is going to work 9-5 (not even a majority of people work these hours in the US): Set it up so that winter equinox has sunset at 7pm. This has the sun coming up at ~9am during winter at the 40th parallel. During the longest days of summer, daylight would be from about 6am to 10pm.

That timing is standard time + 1 all year round.

Looks like 2017-2018 57% percent of workers had flexible schedules: https://www.bls.gov/news.release/flex2.t04.htm
