What is this supposed to mean?

Is it not self evident that the vulnerable tend toward being that subset of the population that, on average, suffer the most.

This usually means the very young, the elderly / frail aged, and those with co-morbidities especially obesity and immunocompromising conditions. There’s also a socioeconomic aspect, where as wealth increases health also tends to increase.

How do we slice it in these cases? Was it the virus that resulted in the worst of the negative health impacts?
