There's a pro-DST lobby because more post-work daylight hours is correlated with higher consumer spending. For that reason, permanent DST is more politically expedient in relation to permanent standard time.

> And if people want to have more light in the evening, then they just leave work earlier. Surely that is easier than permanent daylight savings time.

I don't think it's possible to lobby employers to change their shift hours. It is, in fact, much easier to lobby the government to change the clocks.

> I predict a lot of people will want to move school start to a later hour then.

This is probably a good idea, though... good ideas don't really seem to have much bearing on the way we arrange school schedules.
