> Looking much higher than that. 80+ is 15-20% and 70-79 is 8%

The percentages you're citing are from the Chinese CDC [1] and represent the case fatality rate. They don't represent the infection fatality rate, let alone the overall population mortality. There's a big difference between these numbers which has been repeatedly ignored in the popular media, they keep on taking the scariest one (CFR) and presenting it in an unbalanced context. [2]

(To be fair, CFRs are the numbers we are the most certain about, but when you cherrypick the worst ones like the newspapers do they're also the scariest and least useful.)

The working definition of CFR in the Chinese study is basically people who saw a doctor, were suspected or confirmed of having COVID, and then died. But many other people would have caught the disease and not been seen by a doctor. Most of them would have been milder cases and they wouldn't have died. Key point is this number is not at all indicative of total Covid-related mortality in an exposed population.

The Kirkland story is really tragic, but it's just one data point and doesn't prove that ~15% of all nursing home populations will die. The conditions in other nursing homes could be very different, in fact that nursing home in Kirkland has since been investigated and fined $600,000 for unsafe practices [3].
