It could be worse. Realizing that having more light later in the day allowed for using less power on lighting, the US Government instituted "Double Daylight Saving Time" during World War II. The clocks were set ahead TWO hours for the summer, not just one... But then again, the changeover was for a shorter period of time - we've been gradually lengthening the amount of time we spend on DST in the US and Canada.

It's opposed by agrarian communities and companies offering entertainment that is dependent on a lack of sunlight (such as fireworks displays, naked-eye stellar observation, outdoor projected "movie-in-the-park" presentations or drive-in theaters). As there are more Americans in the former category, DST tends to be more popular in the US.
