It's not that it messes up anyone's life terribly. It's a minor inconvenience, but it slightly inconveniences hundreds of millions of people, and that adds up. If everyone is slightly drowsy, and 0.1% of people have slightly slower reflexes and get in a car accident, that is not to say that those people 'need to reconsider their priorities'. That means that the policy hurts that many people, and the society needs to evaluate whether the benefits outweigh that hurt.

Don’t know why you are getting downvoted for this. Two of my favourite days of the year are when we change the clocks, there is suddenly a shift in what the world looks like at certain times of day and throw things into a different perspective. Permenant DST makes the most sense out of the two options but I like the shift enough that I’d prefer the model we have - I think people’s negativity towards it is due to a dislike of change and a lack of understanding on its origins, it’s sad that the chap who first proposed it didn’t get to see it implemented.

It is very frustrating to small children who don't understand what is happening, and thus it is also very frustrating to their parents.

You just get so, so much roadkill on time change day.
