I had a look at similar numbers a few years back to back up a debate I was having and was surprised. The UK and US spend in the same order of magnitude per capita on public healthcare.

Sadly, though, this isn't good. The US's healthcare budget covers a minority of the population whereas the UK's covers almost everyone. The only reason the US's budget is inflated is due to the extreme inefficiencies and price gouging that are rampant in the US healthcare market.
