What is essential is irrelevant really. Every job is essential to the people who have those jobs. Baseball players have very short careers. The case for college sports is much weaker, but you still have players who will potentially miss their window.

@superjohn said, at some point we will need to just accept that this disease is out there and people get it and move on with living normal lives. I don't think we are there yet, but people thinking it is going away, even in places with low spread, aren't being realistic. Whether half measures or full measures, this is still going to extend indefinitely.
