I agree that we do need to start thinking long term and how do we live with this thing.
We must suppress it though. We can't function with a 50,000 case a day outbreak for years at a time (assuming there really isn't a long lasting immunity). Human beings won't go to work, school, or sports if they're afraid. Throw in our healthcare system isn't set up to handle wave after wave of infections.
The month of May was a good experiment. Most states tried to get on with life, and after four to five weeks, their hospitals got overrun.
It's not going to happen under Trump, but maybe if Biden can take over we get a full on national shutdown. 4-5 weeks, Euro/Asia style. Suppress the virus. Instead of getting down to the 20k cases we had at end of April, we get down to hundreds.
Then we have a plan on how to roll people back into jobs, schools, sports. Then react quickly when cases flare up. Much easier to trace and isolate a few hundred people versus a football stadium crowd.
The thing we do have going for us is the science and treatment will get better. As you said, somehow we have to get this bug to be as lethal as the flu. Vaccines, therapies, and our own immune system adapting over time.
The other discussion is that this pandemic has showed how big of a failure this American experiment has become. I'm not as against capitalism as some on here, but what we have isn't that. It's crony capitalism at best.
This pandemic does provide us with a chance to change how our society and country should look. Healthcare, Universal Income, how we work, play, eat, and of course how we treat one another. Innovation should blossom out of necessity.
I don't think Biden is that guy, but maybe he can surround himself with people who will challenge for a new social contract. Going back to the way things were, that'll just repeat this cycle. That "normal" was the cause for this reality. If we want something better, we have to change for the better.
