I've lived with worse, am now in fact (max 3mbps, and AT&T doesn't come here). In the early 2000s, I made my living over a cellular dedicated dongle (this before everyone had a hotspot). Said dongle was faster than dialup - at least twice as fast! :-)
So, no. I wouldn't move, obviously, since I didn't then and am not now. But your life will be less stressful if you adjust your usage where you can. Also, if you can get a direct phone number the next time a repair person comes out to work on something, you may find you get faster fixes.
Fiber is coming, even out here in the sticks. It may take a while, but people laughed at me when I said we'd get any sort of wired broadband, and now we have it. How patient are you? :-)
Keep checking for other options, too. Cable is better, and those guys are running more line every chance they get.
