> Both the UK and NY State had a policy of sending recovering (but potentially contagious) older covid patients back to nursing homes and it would have exacerbated the mortality rate vs regions that did a better job at protecting the elderly.
Isn't the death rate the percentage of population that dies when all are infected? Then nothing can be "exacerbated" by that alone? It then just reflects the death rate which results from the people being infected, no matter the speed?
The rate quoted by the parent, I believe, is the number of deaths divided by the number of people estimated to be infected, by prorating an antibody test sampling to the wider population. So that doesn’t assume everyone got exposed to the virus, and assumes the sampling is a representative sample (but in NY it was sampled in grocery stores, which tells you nothing about infection rate in nursing homes that made up 40% of the deaths).

To get the rate one can indeed calculate it with smaller representative sample, but that just doesn't imply that the vulnerable people would somehow never become infected if the epidemic continues, so the deaths of the old can't be avoided then. That the old die much more is a fact, and nothing that by itself "exacerbates" the rate.
Edit: I haven't seen any argument that estimated more than 20% of NY population that were supposedly infected were somehow specially skewed sample to hit only old people, and I'd argue that if the sample is that big it's quite improbable. If the argument is that the virus got faster in the nursing homes, one can also argue that all the old people outside of nursing homes skewed in the another direction by managing to initially not get the infection, but that as epidemic progresses they would indeed eventually become infected and suffer.
Edit2: "the virus is rather showing signs of going away" claim is very curious to me. I don't see it "going away" looking at all the statistics across the different parts of the world. I see only the slowdown of the spread, which corresponds to people generally changing their behavior to slow it down.
But that sample may not be representative of the demographics of the people who got infected. It is possible that a lot more people in care homes have been infected than the grocery store sample, because of the policy of sending covid patients there (and the fact that the staff must have physical contact with each of the patients every day and therefore it will spread within a care home may very quickly).
If it is the case, you don't expect the same death rate to scale up as the wider population continues to get infected (if it is still happening, the virus is rather showing signs of going away).
