Here's the perspective from down-under ...
Most drugs here cost less than do the same drug in the US (less in Australian dollars, which means after the conversion they are appreciably less). Plus, the Medicare system here only requires you to pay the first $20 or so of your prescription, then then Medicare pays the rest. Of course, not all drugs are covered under Medicare, so if you want something not covered (for example, Propecia), then you're out of luck unless you have private health care (which costs extra money, about A$50 or so a month).
Same for medical procedures and doctors appointments. Typical 20 minute doctor's consultation is about A$45, and medicare chips in A$32 of that.
HOWEVER, the cost of living in Australia, and in many other countries, is radically more expensive than it is in the US. In Australia, prices, after conversion, are still 33% to 250% more expensive than the same item in the US. Thus, while the US might be gouging itself in terms of meds and health care, the overall cost of living in the US is still considerably lower than in other countries. Sooo ... let's not get completely anti-US here. US health care system sure as hell has its flaws, but all-in-all our dollar goes a lot further than it does in most other industrialized countries.
