Why does it have to be a centrally coordinated shift? This is a decision that can be done in a decentralized way.
Outdoor venues already have seasonally shifting time tables. Schools in some places have successfully shifted from starting at 8:00 to 7:30 or 8:30. Shops adjust their opening hours all the time as well.
Because actions in society have to be coordinated and done in a certain order. What happens when suddenly your kids school starts an hour later but you still have to be at work at the same time? Many many things are based on routines at a set time each day that people plan for. If there’s going to be a seasonal change, it needs to be coordinated to not cause massive inconvenience. That’s what DST does.
The argument is basically "if the state-sponsored babysitters change their hours partway through the year it will be a massive headache for parents". But if such babysitting is so crucial to a functioning society, surely society can become a bit less rigid to accommodate it?
Yeah, and they can decide for themselves what their start times are.
We don't need 300 millon people to experience jet lag twice a year to save some bougy superintendent the inconvenience of scribbling out a number and writing a different one one time.
The people who really dislike the state don't use the state's schools anyway; this is more like "The post office, the courts, and the banks have done this for decades," so other businesses and individuals also find it convenient to use the same time conventions.
To be clear, I think educators should and do serve a much more important role in society than mere babysitters. My choice of words was because so many people are raising the issue of “what about parents with rigid work schedules” as if school only exists so parents can work.
