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.
However the US subsidizes European defense (refer to current events) allowing European countries to spend less GDP on their military.
Talent comes to the US from all over the world. That's how it works and has since almost the beginning of the country.
Easier access to capital (and easy bankruptcy, etc), entrepreneurial mindset (less Tall Poppy syndrome), etc etc means business is generally easier in US.
Linus moved to the US. The web was possible bc the internet was funded by the US (arpanet, etc).
Europeans enjoy the Pax Americana without paying tribute to the Amerian empire.

But I like the Linus argument, however this complicates things further: Are tech becoming European when the tech CEO's are having a vacation in the French riviera?
And by the way Europe has nukes.
Also, why do you think that the European live longer thanks to the medicine developed in the USA? Maybe the USA develops medicine thanks to the free and equal opportunity education culture in the Europe? If you look closely to the researchers, you will see that lot's of the people who develop these things have European roots and by roots I don't mean their grandpa was Irish, I mean they were educated in Europe and it just happens that the organisation that develops these drugs is incorporated in the USA.
The tech revolution that changed the world was also developed in Europe, the web was developed by the British in EU, Linux was made by a Finnish guy called Linus.
Also, we are at a verge of AI revolution and some of the leading researchers are Europe educated people.
Maybe the USA is just the industrial zone off Europe? Maybe the US appears rich and acts poor simply because because the richness comes from the accounting choices? Just kidding of course, the USA is a superpower and is actually rich thanks to many things like it's abundant resources and brilliant people but the notion that the Europe is doing better because they just drink smoothies and meditate all day on the American resources and innovation is ridiculous.
