"My point is the developed world is no longer a refuge from the hazards of the less-developed world..."
The developed world is full of places you could never, ever afford to live or even visit. Maybe none of us.
So comparing the developed world to the less developed is just foolish.
From my developed world, things are a hell of a lot better, than my less developed world
Fire, Ambulance, Police 1 mile away
Hospital 2 miles away
All stores, banks, restaurants 2 miles away
Never been affected by crime, police falsely blocking the road or arresting me for no reason.
VA health care, maximum set waiting period of 15 minutes at my location
Beach with zero plastic or trash in the water
No psychotic traffic or drivers
No one burning fields or trash out in the open
Clean water
It all depends where you live in the developed world. If you chose a <deleted>-hole, that is what you got.
But to say the developed world in no longer a refuge from the third world? Well is sure as heck is where I live.
