It certainly has been tried, and it's ongoing.
E.g. in much of Europe you're not getting a driving licence without passing a first aid+CPR course, and every car must have a first aid kit and a fire extinguisher.
Also, I recall that USSR had mandatory civil defence courses in universities - so everyone with a college degree, no matter if it's medicine or math, will have had a full semester of disaster followup & related issues; didn't USA have something similar during the cold war?
Most first-world countries are not obsessed with self-elevation and interest resulting from their own infrastructure breaking down
Third-world countries might be more the incubator you're hoping for but they generally don't care what happens to the non wealthy (and the wealthy's FO plans there as with everywhere don't involve looting cars on interstates)
So if I were to guess, I'd go with no, no "other countries have tried this out".
