Total US expenditure on health is much more than government expenditure because it is a heavily privatised system. The total is a very unhealthy 16+% of GDP (and rising), partly due to it being privatised and run as a profit making business, ie the 'wealth care' industry. Nearly every other OECD country health system cost less than around 11% of GDP, and quite frankly you don't want to spend much more than that, it's the law of diminishing returns. Also the US gets very poor returns for it's health dollar, by most parameters of 'health measurement' the US is in the bottom half of the table for OECD countries. (except for access to scanners, where the US is number one). So the US spends way more and seemingly get a lot less.
Having some sort of 'universal health insurance/cover' is sensible and a feature of a civilised country. To an outsider the way 'Obamacare' gets vilified is amazing, the outright lies and deception. Got to be a lot of 'Big Pharma' (an other beneficiaries) dollars behind a huge project like that.
Volkodav, sad to hear your stuck in hospital, nothing more boring than that. Hope all is well soon.
