I read the responses to this thread, and I'm both agreeing that the US could have done more, and also wanting to defend what the US did right. there are a ton of people on the front lines, healthworkers, but also food processing, delivery people etc that kept working despite being in a pandemic. The US was overrun. Not nationally but there were areas that broke down. I know that because I work at the VA and our "forth mission" is to help in national (usually natural) disasters. The majority of this help was in helping testing for COVID (primarily nursing homes) to get a handle and isolate active cases. But also in some places (NY, MI) the VA also admitted civilians into the VA hospitals because the civilian hospitals were beyond capacity.
Our biggest achilles heel is that we love states rights. So many many things including health coverage, and dissemination, etc is done on a state level versus a national level. The VA being able to pivot and in addition to caring for veterans, also help with 4th mission, shows that there is a lot of benefit if we had a stronger nation-wide response to this pandemic, everything from identifying the problem, advertising the problem, having coordinated stay at home orders, and of course distribution of materials and treatments. Individuals did amazing. But response from the top of government leadership was, lacking. And it cost lives.
PS I can give an example where masks DO reduce transmission (I know, a n of 1). But a family friend, actually 3 members of the family came over to play a game, and then one of them came over to tutor my youngest. They were a couple feet next to each other, indoors, both wearing masks for an hour. The tutor the following week feels sick. Even though she thinks its a cold I say lets cancel tutoring for this week. The tutor then tests positive for COVID. I find out, I test my kids, and -negative. I don't really know when the tutor was exposed. All I know is that we missed a bullet and having them both wear masks may have helped. I am primarily using cloth masks I bought from etsy that I like because they have 2 layers and a nose wire so they fit better.
The deal I've seen with non mask wearers, is that in general they simply do not seem to give a fig about increasing themselves or other people's risk. It's not just that they are not wearing a mask. But that they are not wearing a mask inside, or not wearing it and walking close to people, or not wearing a mask where it is clearly stated mask enforcement is in place. there are a number of times and places I don't wear a mask (i.e. outside, being away from other people); never been yelled at or called out. If someone is getting yelled at for not wearing a mask, 9/10 times I have a strong suspicion the person is being an asshole.
ps there are lots of epidemiologic studies that show mask wearing on a population level reduces R. You just have to look at many Asian countries (many which have returned to close to life as usual) to understand this is true.
