Hi Bruce, I think you may be the right guy to solve this. I too remember the days of dry wire sold by the RBOCs.
I found a structured wire fire alarm install to cost $100k for our building or $20k per unit. The labor and materials is about $25k. The other $75k is liability related costs, similar to a bike helmet, $10 in parts, $40 in insurance. So it's not labor nor equipment that drives the expenses. My opinion is poor people shouldn't have to pay for insurance to insurance companies, companies that figure figures for a living. A digression: I could do an LMR 600 passive cable system looped with Wilkinson power dividers, patch antennas and nests to protect the egress escape ladder for about $10 to $15K. Don't need an SLA. We've basically priced protecting human lives to only rich people. We need to use technology and our cleverness to fix this version of "expense bloat." Look at Boston public water for an example. Way too expensive to pipe water in from 15 miles away in the early days. So people who did it claimed alcoholism (and that "immorality") would be eliminated by providing clean and pure potable public water. Alcholics would choose pathogen free water over spirits. Rich people got enough water for themselves and even for their private fountains so society stopped this initiative. It was a motivated doctor who taught rich people that their health was tied to public health. And public health was being impacted because pathogens being spread to poor people who didn't get potable public water would by addressed by ubiquitous potable water supplies. The fire chief was put in charge. See Ties That Bind https://upittpress.org/books/9780822961475/ Now, in the U.S, most do get potable water even to flush a toilet. It's taken for granted. I think it's on us to do similar for digital communication networks. They're needed far beyond entertainment, and we need to get public safety elements engaged too.
