There was a great deal of debate over DST during the petro crisis of the early 1970s. Proposal then was to make DST the year-round standard for further energy saving--if DST really saves energy at all. One debating point was the specter of millions of children waiting for school buses in the pitch dark. There were in fact a few highly publicized incidents of kids getting hit by the road side at oh-dark-thirty. Permanent DST proposal died, although the start and end dates were (much) later shifted to elongate the DST period.
Another motivation for DST, I was told as a kid, was to encourage working stiffs to cultivate vegetable gardens. DST was a war measure after all, and food was a critical resource. What impact DST ever had on the dinner table is moot, but on paper at least it gave the old man an extra hour to hoe his tomato patch before dark. . .

And then there are the clocks we have that automatically do DST--but which predate the semi-recent date adjustment. So instead of having to adjust the clocks twice a year like most clocks, we have to adjust these FOUR times a year. Yay. And no, there's no switch to disable it (so I guess they never wanted to sell 'em in Indiana or most of Arizona).
