Honestly this has been extensively studied and the "the US gets shocking value for money and poor health outcomes" is the consensus. You can either take that as a personal insult, dig your heels in and say "the data is wrong" or "they're lying", blame immigrants or other things I've seen some Americans do when their "we're #1" belief is challenged ... or you can take notice and demand better from your country.
It is really of no consequence to me which you choose, I don't live there and it's looking likely I'll probably skip even visiting let alone consider moving there in future.
