> Drugs get developed because Americans will pay for them, then when the cost is mostly recouped (ie. a decade later), it finally becomes available in Europe.
Does anyone have any reputable cites for this please?
That doesn't follow at all; foreign drug companies sell plenty of drugs to Americans. The test of that assertion is to look at when drugs have been introduced to different markets, compared to R&D costs and the price the manufacturer got for them.
