Out of the 29 OECD countries USA is the one ranking first in highest health expenditure per person (around $9200 a year) opposed to the 3500€/year for Denmark as example (these numbers take everything in consideration, direct spending, taxes, insurance cotisation, etc ...).

So to put it in a nutshell the average American receive the lowest (or one of the lowest) level of service of the OECD countries despite being the one paying the most money for it by far. Nice system you got here, who could expect that private companies would rather inflate their dividends and capital instead of helping people get better?
And the fact that people keep blindly defending it is incredible.
