I wouldn't know, and do not care about has been right wing talking points for ages. Additionally it is very easy to prove on several levels.
For instance the pricing structure of prescription medication while complicated is at least partially based on a percentage of a country's median income. Poorer countries pay less, richer countries pay more. A particular average to produce a particular return is almost always important to a company.
That is one hell of an asumption. Yes prices in a country are often dictated by the median income of said country.. thats kinda logical. After all you cant pay 2 dollars for a cola in a country where the mean income is 30 dollars. Now this is so for all products sold, food, cars, and so on. On top of that we have taxes and other stuff that also influence the price.
Now for your idea to work and to justify the much higher prices for drugs and healthcare in the US as a general, it would mean the median income in the US would have to be much higher than that of European countries to explain the difference, and I hate to break it to you, but several European countries have higher median incomes, and most are near or the same as the US.
Some countries have price controls, some do not. Again the manufacturer is looking for a return. If they must sell to one cheaply, then in turn they must sell to another at higher prices.
Yes its called price discrimination and it only works if the consumer is not 100% informed about prices and able to get at alternative products or the same product in another area. One way to prevent the consumer in doing this is, is banning the import of drugs from other countries. Another way is to ban the biggest single consumer in negotiating prices with the supplyer freely. Add the 2 together and you have the perfect enviroment to charge almost any price you want and with goverment approval. If you can get the other companies in the industry to start a cartel (secretly of course) then bang you got a nice deal going. You typically see clear price discrimination near border areas, where locals go across the border to buy beer and so on because its cheaper in the other country. Goverments usually put limits on what you can bring in to slow down or stop said buying.
But lets think about the math a bit. The US has 300 million people.. the world has over 6 billion. So your idea is that the 300 million of the US pay higher prices so that the rest of the world gets lower prices, dispite at least the same amount of people in Europe (acutally more) have similar or higher median incomes than the people in the US? Does not add up even without doing any numbers, if we consider that drug prices are "the same" world wide in production.
The North American pharama sales account for about 48% of the world sales in dollars, but we have to remember the prices are higher so that is only natural that the total sales amount is higher too. But the question is will the 48% cover not only the costs in country, but also part of the 6 billion other people on the planet? I have my doubts, but would love to see any studies done on it if anyone has any.
Add to that, that European prices are on average higher than American prices, because of tax and so on, and the idea kinda falls apart.. not to mention the currency difference through the years.
I know for a fact that drug prices in Denmark are higher than American prices, as we have several companies attempting to import stuff to sell in Denmark and they could not do that if american prices were higher. Now they have been blocked for safety reasons quite often (funny eh?) but some have succeded after taking it to the courts. This goes on a wide variety of goods btw, from contact lenses to computers and so on.
Also your idea has to mean the manufacturer is "fair" and "ethical".. and since when have they ever been that? They are greedy, its in their nature. If they can take a higher price for a life or death giving drug because no regulation or oversight prevents this, then they will. If a car manufacture does not have to recall 3 million cars because 2 cars blew up, then they dont. The fear of billion dollar lawsuits or regulation requiring recalls, forces them to do it. If they can dumb thier waste free of charge without getting caught or if the price is low for getting caught.. then they will. History has shown this time and time again. The free market is not perfect, far from it. It is however the best we got and sometimes it needs a bit of "checking" so it does not go totaly wacko.
The facts of drugs prices, healthcare costs and similar things are just not in the US favor. You pay over double the amount in healthcare costs per capita and in % of GNI than similar nations, your infant mortality rate is one of the highest in the western world, your life expectancy is one of the lowest and your system does not cover every person living in the US. The question is how can Americans keep accepting to pay so much for so little? And will blaming outsiders for this keeping going on even though there is no proof to back up such claims?
Actually I did not blame anyone, but if pricing is partially based on a percentage of a country's median income, I do not believe my statement (The bottom line "seems" to me to be that our "relatively closed" (More expensive) system is subsidizing cheaper prescription drug prices in other countries) is too far "right wing," or off the mark.
As I have stated, I think its off the mark

As for right wing comment, its more the attitude towards it all. Blame outsiders or the weak for ones own problems.
The debate so far has always been centered on 2 things as far as I can see.
1. Prices are high because we subsidize other countries drugs. Prove it.
2. Prices are high because people sue so much. Partly true, but that is again blaming someone else instead of looking at the system it self.
Why no debate over the laws preventing a free market? Why no debate over your whole healthcare system? HMOs? and so on? Why constantly blaming "outsiders" or the weak or those you dont like?
Now I am not saying that the Europeans have a better system, but we have a different one. Very few countries have price controls (its kinda illegal with in the EU), which is another argument the right has thrown into the debate to sour it... as price controls = communist and that turns off most Americans right off.
We have at worst price oversight, which means goverments keep an eye on prices to make sure that drug companies dont charge exessively. We also have a free market, which means that hospitals and so on, can acuatlly negotiate for better prices instead of being forced to accept whatever price the drug company dictates. We can also import drugs from other countries within the EU and other "safe" areas. And its not illegal for me to buy drugs in Spain and import them to Denmark for personal use. Of course I would need a licience to set up shop to do that, but so would you in the states.
Its time America has an honest and total debate, not dismissing things off hand because they are socialsist, communist or "european" ideas or ways of doing things.
