The difference between "overwhelmed" and "not overwhelmed" is pretty subtle. You can measure this in ICU beds and hospital capacity, but that's not sustainable. You have to start asking "How many hours are health care workers working?". You also have to ask, if we did have any setbacks/outbreaks, what buffer do we have in terms of people and PPE availability?
You can't run the system at the red line, it's not sustainable. And any distance between our current capactity and that red line is somewhat open to interpretation, but I bet that distance feels a lot smaller for our EMTs and Doctors than it does for the average person on HN.
In April doctors were pondering why there was 40% to 60% heart attack patients. https://www.nytimes.com/2020/04/06/well/live/coronavirus-doc...
It's a collective action problem. If everyone keeps to mask mandate and social distancing for a month, there is no need to close gyms and schools after. Germany and Italy are fine now with maybe ten deaths a day.
If 20% of the population keeps ignoring the recommendations because they don't give a flying fuck about the society they live in, R0 will stay above 1 forever and half of your neighbourhood will see their grandparents die in the next year.

Pandemic control measures can temporarily suppress R0, but as soon as those measures are lifted the contagion picks up again.
The average age of grandparents in the US is about 65. The actual infection fatality rate for that age group is 1.3%. That's bad, but nowhere near half the neighborhood.
