Yeah, because uprooting your whole life to avoid having to deal with Daylight Savings Time is totally worth it.

People always forget in these if "If you don't like something, go to some place where things are different." or "If you don't like some aspect of a service, drop it." slogans that there is more than one factor to consider in where people or live or what services they have. You may avoid Daylight Savings Time in living in Arizona, but what if you don't like living in a desert region? Or leaving all your friends? Or don't want to quit your job? Or whatever?
Anyhow, as someone who lived in Arizona briefly, it's worth mentioning that you actually don't avoid the effects of Daylight Savings Time by living there. For one thing, your television basically goes haywire scheduling wise. The local OTA affiliates stay the same, but any east or west coast feeds you get on cable or satellite move with the time change, and so do sporting events that take place in other parts of the country. And then you're no longer 2 hours off the east coast, you're 3 hours off, which gets confusing even arranging phone calls and stuff with people you know in other time zones. And even adjoining states within your time zone all the sudden are operating on a different clock than you are- it's like Arizona becomes it's own separate time zone during DST, or temporarily moves to the Pacific Time Zone and then returns to Mountain Time and then back every single year. It's chaotic.
Arizona kind of has it right, but the rest of the country doing things differently screws things up for Arizona. At this point, they as might as well just do things the way everyone else does things to avoid the mass confusion that hits when everyone else changes and they don't.
It's like if you loved laserdisc back in the day and were truly convinced in your heart that it was much better than DVD, eventually you probably switched over to DVD just because they stopped making laserdiscs and you could only buy or rent or borrow from your library or friends if you made the switch to DVD. Even if you were right and laserdisc was better, at some point which is better became a moot point, and it made sense to just admit defeat and move on and do what the rest of the world does for the sake of convenience. I mean, keeping your old laserdisc machine and discs you already had probably made sense, but at some point you were going to go out and buy a DVD player unless you were exceptionally stubborn.
