Sure but the current state of affairs is clearly not optimal from an individual patients perspective. You notice this as you hit 40, 50 years old.
I know multiple "woops we don't screen often/early/proactively for that" cancer deaths in mid 30s to mid 50s.
I even know a few "wow good thing you had that CT scan for xyz, we just found some unrelated Stage 2 cancer elsewhere" people.
I know ZERO "oops false positive, we killed you with an invasive procedure" deaths. I know they happen, just clear to me its less often than the above.
Maybe you are young and/or lucky, but you'll find over time an increasingly disconcerting amount of friends&family dying preventable/otherwise treatable (with screening) deaths from cancer.
Note I said "from an individuals perspective". It is possible for the system to be optimized from a cost/benefit system level perspective without it providing the best possible outcome for each individual. Given that its run by the government & for-profit insurance, this is probably the case.
I think it is a bit hard to argue that the US medical system in general is perfect, and beyond reproach. Let alone the gaps in our pro-active cancer screening. Places like South Korea and China do far more, with less.
