It's not enough for there to be an increase in cases anymore, even a significant one. Of course cases are going to go up. Why wouldn't they? This was not initially about case numbers, it was about isolating the mildly sick and offering resources to the gravely ill. The lockdown made that more than a faint possibility.
Unless there is a NYC esque scenario where major cities like LA, Chicago, Dallas, Miami, etc experience hospital surges that result in tens of thousands of new deaths per city, rolling back the lockdown would be a disaster politically and economically.
The sad reality is that the current lockdown was a failure because our citizens are stubborn idiots and their leaders largely let them down. No unity, no clarity, no plan. Some lives were preserved, but 3 months have passed and where are we? Daily deaths are down by about half of where they were at the peak and continue to slowly drop. We're pulling in about 7,000 fewer cases a day than we were early April. But the virus hasn't gone anywhere. And, frankly, people just don't care anymore. The protests showed how quickly a worldwide pandemic of all things can become old news.
The only option is to move forward and hope that habits caused by familiar CDC guidelines will keep the spread from overwhelming communities. We know what works now and have the data to back it up. ENFORCE masks, don't just encourage them. Develop contact tracing. Expand testing. Allow people to live their lives while making them take the guidelines seriously. Personally, I'm keeping my ass indoors for now.
