If I had to guess they are probably going to structure this so that it targets poor neighborhoods who are less likely to have the resources to sue. You can do that by breaking up a city into subsidies or parishes or what not. Which is exactly why you see that so often. Rich people like to have the services of a large city but they don't like the pay for them because well you don't get rich paying for things you get rich making other people pay for things for you. So wealthy people will split their part of the city off so they don't have to pay taxes while enjoying the services of the rest of the city
As always it's a big club and you ain't in it.
You're right, but....the wealthy typically call 911 less. They're less likely to be victims of crime. They're more likely to keep up on routine checkup and take their medication to find chronic problems early. They tend to drop dead at a much later age....plus, being poor really sucks and is one of the most stressful experiences a human can go through....it definitely takes a toll on you physically, so you are more likely to drop dead.
How many health studies have simply been a proxy for wealth and thus stress? Remember when they thought drinking wine was better for the heart? How about tooth decay?...when they linked bad teeth to heart attacks. I think there were ones posted here related to air pollution. It seems like 4x a year, they come out with some study about how one group outlives the other...and in pretty much every case, the behavior of the group with worse outcomes is noticeably more common among the poor than wealthy. Being poor is deadly.
From a cold-hearted economic standpoint, it would make more sense to use human operators for rich districts and technology augmented services for the poor. Not only are they more likely to sue as you pointed out, they also will call in lower volumes. I grew up in poverty and spend my college years living in the inner city around violence. I now live in a nice neighborhood. There's a lot less first responders being called near me now than when I was surrounded by housing projects.
Also, it's not really New Orleans' fault the rich sue and the poor consume huge volumes of services. I take them at their word that they're just trying to provide services to the best of their ability. If they cannot afford a huge staff of human responders AI, could increase response times.
