"All" is doing a lot of work there. My experience in Massachusetts, for example, is that there was quite a high rate of compliance with public masking rules in general. Yes, some people were sloppy about wearing them and many wore less effective masks. But I saw very little outright refusal in indoor public places.

Followed every rule perfectly? That sounds about right. That's really not that important though.

But half of the US at least is actively hostile to doing anything to help anyone. Our society is broken and doomed.
