Go into detail about what the problems were and why everyone hated it.
People with school aged children were upset that their children were leaving for school in the dark.
People had more accidents in the morning (but accidents in the afternoon and evening hours decreased, especially pedestrian fatalities.
They didn't even try it out for a prolonged period of time and a lot of that had to do with the Watergate scandal and the Nixon presidency.
Also the health benefits of switching to Standard time and doing away with DST would work with permanent DST too. The major health problems that are caused by the current model have to do with altering the bodies internal clock, and you get the benefits of not having to change regardless of whether we choose permant Standard time or permanent DST.
For reference purposes, car accidents spike significantly after DST ends, not just when it starts.
I think the main issue with their attempt in the 70's is that they didn't try to change the hours of school and work to make things more workable. We didn't do that because it would have forced major industries to shift things and that seemed like too much work.
This would make things safer in general and fix sleep deprevation and other sleep related maladies in the vast majority of people who aren't morning people.
And having more natural light during the waking hours decreases the amount of electricity used, can decrease heating and cooling bills, etc.
People complain about the idea (either moving permanent to standard time or morning permanently to DST) literally based on vibes. Nobody seems to give it a chance with actual changes to make it work for any length of time.
I'm also going to point out that a lot of the problem full stop is that Americans just do not have significant amounts of free time.
