The problem with saying "we are all in this together" is that we aren't. Some people are able to work from home, some jobs are considered "essential." Other people are out of work, others have their businesses shut down, and have lost their life savings. The virus can wreck and kill some people, and others will be fine in a few days. We are not all being affected equally, which makes it harder to address it equally.
That's why we owe to each other to all row in the same direction. I'm one of the lucky ones, I'm working from home, I didn't lose a penny over the virus - heck, I even saved some because I no longer take the subway. I'm trying to do my part, I'm not always going around, I wear the mask and deliberately avoid every single person that comes my way, to the point that probably I'm overdoing it because you don't catch the virus by a random stranger that, while being silent, walks you by for less of a second... still, I'm staying away from *everyone*
If I don't get the virus the few family people I interact with don't get it, and if they don't get it, they don't give it to someone else, and those someone else don't give it to someone else still and so on. I like a saying that goes "No drop believes to be responsable for the flood", well, if we all don't spread our droplets around, the chain of contagion ends and those people who are suffering economically from it will no longer have their shops closed.
Also, we all need to go and see concerts in 2021 so we'd all better stand united because there is no way in hell I'm gonna miss Iron Maiden in summer 2021, let's all be prepared in time
