You misremember. It's an argument that many have for abandoning DST altogether and sticking with standard, sane time zone hours, not keeping DST
DST year round in northern states (or countries) would probably mean schools would have to adjust their schedules in winter, starting later, and running later.
Here in Alberta we have a premier who fancies herself as a donald trump sort of leader (she's a stable genius), so she got her party to pass a law to make DST year round here, never mind that only a few short years ago a referendum came down decidedly against year-round DST. Had the referendum been about keeping standard time year round, it would have been a landslide "yes." But she knows best, democracy be damned.
Personally I want standard time all year long. But changing clocks, as dumb as it is, is preferable to DST in winter. Honestly the time change has never bothered me. I haven't really noticed it in decades. Laptop, tablet, cell phone time all change automatically and alarms ring when they should. If people stopped thinking so much about the time change and using it as an excuse for their ills, it would affect their health less. It's like my relatives that lived abroad their entire lives, but every time they'd make the trip back here for the summer they'd complain endlessly about jetlag and constantly look at their watches and say, "oh it's 3am back home." Whereas when I travel I change my watch and phone to the destination time zone the minute I get on the plane, and then never think of my home time for the duration of the trip. Still get tired and exhausted but can adapt faster without my brain constantly thinking of the time difference.
