If you ever want to "sanewash" healthcare spending in the US, this random guy stood up an entire website to argue that per-capita healthcare spending in the US is more or less in line with expectations based on per-capita income:

TL;DR: As people/countries get richer, a larger share of their money goes towards consumption. It's not just that Americans pay more for the same procedures (sometimes they do, sometimes it's just sticker prices) but we consume more healthcare the more money we make. So it skews costs up disproportionally. That wealth also enables chronic health and lifestyle problems that are expensive in their own right.

I'm not sure I'd buy the theory entirely, but it's very well argued and as a null hypothesis it makes a lot of sense.

My personal experience is that people in the US feel much more entitled to consume medical services than people in the country I came from (UK). They are richer, but there's a cultural difference too.
