At least in the US, this all has exposed a lot of the problems with various systems, some of which are still not getting very much attention. And there are structural problems this will lay bare, such as the injustice as well as economic stupidity of not having public single payer healthcare. There is unacceptable inequity.
So shouldn't anger and resentment be justifiable?
I guess I'm not sure what the author is looking for. For everyone to pretend the problems laid bare by the epidemic don't exist?
My guess is the next wave of this is when the lockdowns are lifted because the economic costs become too much to bear, and then the deaths and illness still increase — when people realize you can have a lockdown and still afterwards have a growth in cases because there's no vaccine or herd immunity. I suspect things will return to normal and become better in many ways, but become very unfamiliar and worse in others.
