Myopic and ill informed.
> A 2017 study in the American Economic Journal: Applied Economics estimated that "the transition into DST caused over 30 deaths at a social cost of $275 million annually", primarily by increasing sleep deprivation.[128]
From https://en.wikipedia.org/wiki/Daylight_saving_time, Effects on Health section. That section mentions many more negative effects of DST.
> An LSE study found that DST transition increases people's feeling of being rushed for time, and the number of hours spent on leisure decreases by roughly 10 minutes following the transition and more specifically the spring transition into DST decreases life satisfaction by around 1.44 per cent.
I think this summarizes it. The negative effects are concentrated around the transition. The positive effects are spread throughout the year. You lose 1.44% life satisfaction for a few days, and gain immeasurably more over the course of the year.
