Permanent DST is just a synonym for "let's all agree to wake up an hour earlier." The same change could be affected by e.g. schools and businesses agreeing to open at 8am instead of 9am. (Of course that would be wildly unpopular so permanent DST is just way to trick people into swallowing the pill.)

But would behavior change in the long run? Countries like Spain where solar noon differs wildly from clock noon just end up aligning their rituals accordingly (e.g. eating dinner at 9pm).

School starts at 8am everywhere that I know of in northern New England and always has? Does school start at 9am where you live?

And as noted, an 8am start to the working day is long established in certain parts of Vermont and New Hampshire. It has not been "widely unpopular." It's nice to get a few minutes of sunlight and twilight after work in winter.

People may adjust their eating times or leisure activities, but work is 9 to 5. It's amazing to have almost 5 hours of sunlight after work
