I think that is the key distinction...
The volume, combined with how easy something is to effectively prevent.
At it's essence, a large percentage of people who end up in a hospital bed, do so because of a bad decision.
Whether it's the guy who has a heart attack after 40 years of eating terrible food
Or the lady who decided it was a good idea to smoke a pack a day for 40 years
Or the kid who decides he's going to try to jump a four-wheeler over a truck in the backyard
What makes the covid situation unique is that it's a massive influx all happening at once, and it's one of the few things (that cause such levels of hospitalizations) that can be largely prevented regardless of prior poor decision making.
For instance, there's no such thing as an injection that can prevent 80% of lung cancer hospitalizations and deaths among long time smokers. If there was, I'm sure every smoker would be glad to take it.
For covid, there's such a quick solution for drastically reducing your hospitalization risk from the more severe outcomes. And the people who willfully refuse it are the ones who are taking up a disproportionate number of beds compared to their share of the population.
