> Let's look at infections per capita, where U.S. is currently 12 out of 215--significantly higher than any other western democracy, even those that have done more testing per capita.
Sure, but according to that source it's also among the middle of the pack of developed countries in the mortality rate, and considering the relatively high testing rate in the US compared to other developed countries the mortality rate seems like a slightly better first approximation. It seems like you considered the high infection rate but didn't adjust for the high testing rate besides noting that some of the countries with more testing have a lower infection rate. This ignores the countries with a lower rating rate and similar or higher mortality.
