It's a bit disingenuous to suggest that accidents like this don't also happen in the U.S. (or other "first-world" countries). In the mid-to-late '90s I was working on a project that had a fatal accident in the Omaha NE area (fortunately I wasn't present to witness it).
Another contractor was lacing new fiber-optic cable to the existing coaxial cable and realized they'd run the fiber over a safety ground about 7 poles back. Rather than unlace that much cable, they opted to lift the safety ground, move it outside the fiber and reconnect the ground. These ground wires are not supposed to be carrying current when things are working correctly - this one was an it electrocuted those working on it.
Regulations are pretty explicit about how to add cable and telephone wires to a power pole ... and only the power company is supposed to mess with the power. The SCTE and NCTA both have training regimens that obsess over safety, especially when you're working around power (since none of us are actually power experts).
So why did this accident happen? The workers were contractors of contractors of contractors who got paid by the mile. The more fiber they laced up in a day, the more they got paid. They knew there was a slight risk the ground wire would be hot once disconnected but they chose to ignore it for financial reasons.
I've seen tall scaffolding on wheels being moved around in the U.S. and I'm hoping the workers were well versed in the perils of letting their metal structure touch power lines, but what you can't tell from this video is how well these workers were trained and whether they realized the wire they hit was active.
I'm not disagreeing with your article's main points ... that we need to value human life and protect the environment. But I also don't think this video is particularly good at promoting those values.
