Masks work best at preventing those who have the virus and may not know it from spreading it further. Since it is impossible to tell if you have it or not before symptoms show, everyone should be wearing one for now when out in public. But this is America, currently the land of “me first” and the land of “my freedom is more valuable than yours.” I hope in time we will become an America where we have gotten over those childish traits. BTW, interesting that can tell which channel a poster gets their news from by their comments here.
