lack of healthcare, obesity, poverty, mass incarceration, stigma through politicisation... just to name some of the things that immediately come to mind which COULD certainly impact the age distribution of covid-19 deaths.
Yeah, to be fair, I should have phrased that more precisely: I see no reason why the age breakdown of covid lethality (number of deaths per age group, normalized by the number of cases in that age group) should differ between countries.
Those factors you mention might shift the exposure of various age groups, and thus the distribution of absolute case and death numbers by age, but not the distribution of lethality over the age groups. For example, if more young than old people are incarcerated, then there should be more cases among the young, relative to old folks. But the actual lethality/risk of dying in both groups should remain the same.
Obesity rates should be higher in the U.S. than in other countries by a certain factor, but I see no reason why this factor should significantly vary over age. Say there are twice as many obese people in the U.S. than in Germany - do you think this number comes from 5 times as many young obese Americans than young obese Germans, but only 1.2 times as many old obese Americans than old obese Germans, or vice versa? I really doubt that.
Similarly, poverty, lack of healthcare and stigma should also be flat risk factors whose variation across age should be very similar in different countries. They should not shift the age distribution of lethality and just increase the risk across-the-board.
