A small subset of society (school-children) needing to adjust is much less of a hassle than everyone adjusting though. I'd be curious to see how many subsets of society would prefer changing their clocks, vs keeping them the same.
It's not just schoolchildren. People on HN have a skewed perspective here because we generally don't get in trouble if we're not at work by 9:00 (or earlier). Those who do are more likely to appreciate the extra hour of winter morning sun.
And my point is that since elected representatives across the country and around the world have reviewed DST a number of times over the years and have usually chosen to keep it, the simplest explanation is that it reflects the will of the majority in those locales.
It's possible that it doesn't, but like I said, Occam's Razor makes the simplest explanation the default until evidence to the contrary is presented.
