These reports tend to ignore how fast you can get a specific service or test done. There is plenty of anecdotal data out there that in US you can get CT or MeI the next day, while in many countries in the EU you have to wait months.

I think looking only on the spending per capita tells us nothing about accessibility of service, and its quality. Once you start to consider those things, imo, the whole thing is not as a clear cut as it looks.
