you’re not wrong. But on the other hand, there are events like this. https://www.npr.org/2022/01/03/1069974416/texas-winter-storm...

So at least sometimes, it is life or death.

In North American winter temperatures?

For someone with an oxygen machine, yes it is. Many of those billions just don't have the option for this, they would end up committed to a hospital or dying because the treatment would never be seen as viable.

And now that I say it: hospitals need electricians too. Electricity goes out in a hospital for too long, lots of people die.

And actually a third point: electricity -going out- is not the only thing that could kill a client, it's not too hard to start a fire.
