This is stupid, but fine.
It's stupid that if you make an assertion that you should back it up with evidence? Why doesn't everyone descend to the level of pizzagate conspiracy theorists and anti-vaxxers, that would make a whole lot more sense, wouldn't it!
It amazes me how I take a few hours away for a forum, and idiots start to assume that me not responding means I have no argument. The US in many areas of healthcare does far more. There is far more out there to find as well, but I have a life outside of a tech forum. Gasp, how could it be?
Your last response to me was "you're an idiot"; frankly I don't think anyone was expecting you to respond again after your insult in lieu of an evidence-based argument, because it's the kind of thing that someone with the maturity of a child does when they feel that they've lost. Your last bit of evidence only backs up the assertion that US spending is higher per capita than other countries, but the funny thing is, chart 4 in the PDF shows that the expenses are higher across the board of spending. You also apparently decided to completely ignore table 2. I don't think anyone is challenging the assertion that US medical spending per capita is relatively high (which is all that your evidence so far backs up), perhaps than it ought to be, but just admit that you pulled the assertion you made out of your ass, or got it from somewhere that provided either as much basis for the assertion as you did (which in terms of making assertions with a factual basis, it's as good as making it up on the spot), or you have no idea what their sources are (in which case you have no idea whether it has a solid factual basis).
But it doesn't at all make you look like an arrogant arsehole to then drop another insult aimed at everyone else here to suggest that you're the only one with a life outside of this forum.
Coming back to the topic, if US's higher spending was largely the result of fear of litigation, then it's reasonably logical to assume that if they're sending patients off for "likely to be unnecessary but let's not take the risk" procedures that they would be more likely to detect conditions and thus have better outcomes. However, Japan's and Canada's spending is signficantly lower and also has similarly decent outcomes (charts 4, 5 & 6).
