The point is, it wasn’t the old sick people doing all the spreading in the first place, nor is it just old and sick people overrunning hospitals.
People go back out like nothing happened, we will be right back where we were a couple weeks ago.
On the other side of that. Lots of businesses exist on the fact that they can pack people in by the numbers. Lots of businesses economics don’t work if they can’t pack lots of people in.
Furthermore lots of people habits have changed for good. You open up movie theaters, amusement parks etc, numbers will be down as people are reluctant to go, then the businesses still lose money and can’t pay their employees.
The point of all this is to say “just open back up” isn’t good enough.
There needs to be detailed plans, regulations, support, etc, for businesses and individuals as we all figure out how life works moving forward.
