The loss of pay phones is a really good example of saving pennies and losing essential service as a result of technological progress. When companies started taking them down, local governments should've stepped in to take over or help form a non-profit to maintain these services. There's a number of times where I've been out and about and my phone either can't get service or just inconveniently died on me, and having easy access to a pay phone helps prevent one from being totally stranded. And strangers, rightfully so, are reluctant to share their phone.
