I think we all just got comfortable being “consumers” rather than people whom Hashem granted free will. A 100 years ago, half of the children were dying in childhood, world wars were raging, factory workers went unemployed … now, we B’H live decades in peace and prosperity with 24-hour delivery of anything in the world. There is always somebody out there who did not live to our expectations – did not deliver on time, did not create the right medicine … So, nobody had any vaccines against CVs, and suddenly new technology worked out in less than a year – but, sorry, not perfect, just decreasing death rate by 3-6 times …
with that in mind, if you compare overall pandemic statistics, you can see that US death rate is higher than comparable countries, seemingly due to lack of continuing vaccination and probably lack of other protection measures – especially starting 2021 when there was no more Trump to blame, so libs stopped blaming him and started convincing tired public that everything is great now so that nobody notices how many more deaths happened under Biden who did not introduce one useful idea (I don’t think rent and loan cancellations helped anyone’s health).
