The purpose of a clock, to my mind (and feel free to argue this bit, as it's the premise upon which my argument is based) is to provide a description of the position of the Sun in the sky. A sundial, by definition, always tells accurate solar time. Clocks don't quite tell solar time, they tell an approximation based on the assumption that one noon should be exactly 24 hours from the next. In truth, solar noon (defined as the time at which the disk of the Sun is centered on an imaginary line running from North to South through the sky) varies depending on the time of year by up to fifteen or twenty minutes in either direction. So, 24-hour clocks are a compromise, and noon on the local clocktower was traditionally defined to be "average solar noon for the year, from this location." This is a compromise I'm willing to accept for the sake of consistency and recordkeeping.
There is a second compromise made with modern clocks, and that is time zones. Back in the 1800s, the advent of the railroads necessitated the syncing up of distant clocks for the first time, and (after a lot of confusion for a couple of decades) the railways established Railway Standard Time in 1883. In 1884, an international conference in Washington, DC established both the official Prime Meridian and the modern concept of time zones. A time zone, as conceived, is a slice of 1/24 of the globe, and all clocks within that time zone are synced to average solar noon in the geographical center of that time zone. This is a second compromise, as it clearly decouples local clocks from local noon, but it is another compromise I'm willing to accept for the sake of consistency and recordkeeping.
Daylight savings, on the other hand, was introduced in 1918 by an act of Congress called the Standard Time Act, which set the boundaries of the time zones within the United States, and also dictated that we change our clocks to be an hour earlier for eight months of the year. This one is a bridge too far for me, because it 1) makes the local noon not just loosely but completely decoupled from solar noon and 2) offers no advantages in terms of consistency or recordkeeping. Moreover, it flies flatly in the face of the fundamental purpose of a clock, which again is to describe the current position of the Sun. If we want to collectively have different summer and winter hours, that's fine and strikes me as only a moderately-bad idea, but making the clocks wrong is not the way to accomplish this goal. Rather, we should call a spade a spade and tell people that school is 7-2 and work is 8-4 for eight months out of the year, and only 8-3 and 9-5 for the winter months. Further, hopefully this would make the absurdity of the situation clearer to more of the population, and we could settle on having the summer schedule, but right clocks, all the time.
TL;DR FUCK DAYLIGHT SAVINGS WITH A SPIKED METAL ROD HOW COULD THE 1918 CONGRESS BE SO STUPID
P.S. Arizona is the one sane state that doesn't do DST, your state government has the power to just not.
