buddhism suggests we focus on the things we can control, like perception and attitude in the face of otherwise uncontrollable circumstances. i've no doubt the situation for many medical professionals is quite frustrating, even infuriating, but it would have been so in any of the myriad of realistic scenarios. the virus is, and was always going to be, endemic, which means hospitalization and death rates are pretty well bounded no matter what we realistically did. the frustration comes from believing that this isn't true, that there was something that could be done to significantly reduce these rates, but that's mediopolitical messaging, not realistic possibility. accepting this could possibly relieve some of your frustration.
also, no assumption was involved, just the simple logic of multiplying two tiny numbers resulting in another tiny number.
