To each their own but in USA mask will never be mainstream as in Asia. I'm not an antimasker or whatever. If you want to wear it then wear it. One should follow simple rule if sick then don't go to work or be out in public much but here in USA a lot of low income workers can't afford missing work or have paid time off to be able to miss it. So they show up to work sick.
The reason why USA has more death rates is probably because we are a sick nation. Sure some healthy people that caught it died but majority of deaths are older people and not in best condition of health.
I've probably had it in first few months of outbreak. I was then vaccinated twice with moderna. I was then exposed at work from coworker that showed up for a week coughing working side by side during delta wave. I tested negative after work made us all get tested. Tell me why should I care to wear a mask. I don't encroach on people's space even before pandemic at stores or whatever.
Like any successful virus it is meant to evolve and try spread without killing too many host. So Corona is getting more spreadable but less deadly.
Eventually there will be a compromise between always mask people, anti mask people, etc. If you want to wear a mask wear it. I won't shame you in public but I'll make fun of you to friends in private especially if I see you in a car by yourself wearing a mask.
