Keep in mind FL has gotten there without sacrificing their economy.
Are you claiming that the hundreds of billions in aid the US Government has given Florida was unnecessary? That would be a theft by the Republicans of an epic status. We were told that Florida had a collapsing economy so needed that money, but now you tell us they were doing fine all the time.
My theory here is you are a liar. I know people in Florida, and they confirm what the news is saying, Florida is as much of an economic mess as the rest of the world, if not more.
As for reaching herd immunity, the number of dead are still rising, so we are no where close. We may never reach herd immunity. Antibody immunity seems to fade quickly.
