some scientists expect US cases to peak in January and bottom out in March: If this happens

So, what they are saying is now isn't the worst time. The worst time models wise is in late January and throughout February until March. So, if I foresee this problem it is a different problem than people dying.

The problem becomes so many people getting sick at the same time that there might not be enough people to help other people eat and stay alive because so many people will be out sick at the same time.

So, generally speaking the problem is not people dying from this, the main problem is no one well enough to work if you have millions of people all sick at the same time from the most contagious virus the human race has ever known: Omicron.
