I just don't think people compare the likelihood of dying from cause A to the likelihood of dying from cause B. That is, I doubt anyone looked at this and compared it with say the likelihood of dying in a car accident or from a heart attack, or whatever. Instead, they simply evaluate each event on its own.
For example, I once went whitewater rafting in Colorado. I have no idea how likely or unlikely it was that I could die from that, but my perception, at least, was that while there was some chance, it was still pretty unlikely.
I was thinking about this the other day. I personally do not know anyone who has died of Covid, with one exception. Obviously I've read stories about people I may have heard of who have died from the disease, but I don't have any relatives, friends, employees/co-workers, etc..., who have died. The only person I know is a guy that I used to play in golf tournaments with back in the mid-1970's, and I read his obituary in my hometown paper. He was 92 years old and living in a nursing home and died from the disease.
At the same time, I probably know a dozen people who have died in the last two years from other causes.
I don't think my experience is unique, hence the reason that I believe large segments of society don't see it as a huge threat.
