In the time before the Titanic, some Engineers warned that ships should have more life boats. It took 1514 deaths to convince the world of that (and that radio/telegraph is important to have).
Look at climate change.
Some countries put some effort in, others ignore it or outright sign-out of agreements to limit greenhouse gas emissions.
There is a saying in safety/security/IT "When you want to convince management to look into fire safety, burn down the building across the street."
So for healthcare, I would like to think this was the wake up call many countries needed. Enterprises and competition do not handle worst case scenarios like this, it is on the governments to take precautions.
