You realise that the sun isn't dictated by what time we say it is? If you don't think its reasonable to go to work at 8 during the winter then we should change what time work starts at.
From a computer scientist perspective, I would love that we drop DST. But from the social perspective, this would simply shift the problem.
You apparently consider the problem only from the student or employee point of view. What about shops or public office opening hours ? This would imply changing opening hours. See the problem?
People open when there is business to do. Shops will adjust to changes in footfall. Reaching individuals needs scheduling, and support lines normally cover multiple timezones or 24/7 anyway
