"disproportionately affecting" Always an interesting concept. It pre-supposes that all things should inherently be affected in equality, something I have never seen in reality.
Covid is an amazingly elegant beastie. It affects each person individually according to their baseline physiological weak points, seemingly analyzing where and how to have the most effect. No matter how good the mask, it cannot protect you from a life time of being unhealthy.
The mortality numbers in the US are high while the mortality rates are less disturbing. Canada has less mortality, raw death number-wise, yet nearly triple the mortality rate (confirmed infection to death ratio).
Low socio-economic status results in a generally less healthy lifestyle, lower quality food, less exercise/more sedentary lifestyle, less medical follow up, etc. The basic determinants of health, as a baseline. In comes Covid and finds a population of less healthy individuals...Poof! higher infection rates, higher mortality rates. Covid highlights, and hits, the weakest points within a healthy individual, weakening them further, perhaps unto death, most often not. Leaving the survivor depleted, with an adjusted baseline, that, theoretically, can be restored with time, exercise and commitment. However, if an individual lacked the resources initially to be optimally healthy, it is highly unlikely that they would, after infection and initial recovery, suddenly find themselves in a position to rectify a lifetime of previous lack.
The poor are always hit harder than the wealthy. Again, fundamental determinant of health : Can you afford to be healthy? or are you doing the best you can with what you have?
I suggest that "appropriately affecting" is a more accurate term. There are reasons populations are affected as they are, whether these reasons are readily identifiable is not always clear.
