But it is the only country in the world where German, French, British and Swiss drug companies profit on their R&D. Developing drugs is very, very expensive but manufacturing is very, very cheap. Which means that once the R&D has been paid for (and to be fair... richly profited from) in the the USA the drug companies can also make also make a nice profit on the side by churning out the cheap manufactured product to those places either too poor or too regulated to pay for the initial R&D.
Should the USA ever adopt a less "disgraceful" model that forces the price of pharmaceuticals down to what is paid in the rest of the world, prices in the rest of the world would have to rise and we'd all be paying something somewhere half way between the current USA and World price for drugs. Yes, getting rid of the rich profit margins would account for some of the discrepancy, but not anywhere near all of it.
So if your in Canada or Europe (or just about anywhere else) stop being so eager to change the USA medical system... you'll kill the goose laying cheap pharmaceuticals
