I don't think most of what you wrote, almost phrase by phrase. You took an extreme version of what I said and rebutted it. Just because I said that the US had major influence in European medicine and life expectancy, you took it as meaning that Europeans are bad scientists and "just drink smoothies". I think nothing of this sort.
It's very safe to say that US-originated science had a major influence in life expectancy worldwide, including Europe. What's so controversial about it? The increase in life expectancy in Europe, then, was "significantly" influenced by US innovations.
Of course US "originated" science had influence, just like Russia originated one or Korea originated one. Also, Science is not something you dig from the ground to claim it’s origins. Depending on what you want to claim, you can change your definition. You can claim that we are having it so good thanks to the German science from the 1940s. Pick a cut off date and ownership method to suit your argument needs.
