Healthcare in the US is so expensive because it's a privatized, FOR PROFIT industry. They don't give a shit about taking care of you. They're there to make money, and as any good business people would do, they'll do everything in their power to grow the margins.
Now in places like Canada, UK, Sweden, and so on, it's all nationalized and for the most part, government run. So instead of you personally paying the bill, the government is paying it, so they make damn sure everything is as cheap as possible. And considering the government runs the country, they have quite a bit of bargaining power when it comes to drug companies, equipment companies, wages, etc.
For example, in Canada there's strict laws against drug companies saying you can make a tidy profit, but can't outright rape & pillage people, and basically hold them at hostage (ie. pay this extortionate fee for your drugs, or die), like they do in the US. This is why you see loads of Americans going to Canada to get their prescriptions filled.
That's actually another sad thing about that healthcare law / sham that took place in the US. Originally, it would have opened up access to Canadian (and other country) markets for Americans to buy their prescriptions. Pharmaceutical industry had their influence though, and nope, that portion of the bill was removed. You're buying your drugs from American companies only, damnit!
Too bad the single payer option got left out of the US bill, because without that, there was almost no point to the entire bill. That's the one thing that would have drastically lowered all of your costs.
