Honestly, you're absolutely right. But we don't get to decide between a permanent DST and a unified switchover of business hours across the nation, we get to decide between a permanent DST and the crappy situation we have now. I, for one, would be measurably happier if I had more daytime after 5, because getting one bill passed is a whole lot easier than convincing every single scheduling body that has power over me to switch on a seasonal basis.
