> there are indeed aspects of American life and opportunity that don't currently exist in the EU.

But which are those? As far as I can tell, the only meaningful one I can see is unrestricted access into the US, and the ability to vote for the most powerful government in the world. That's not nothing, but it doesn't have much impact on most people's everyday life, unlike stuff like healthcare and pensions.

I suppose an American living in the EU does get to enjoy the best of both worlds in that regard, but is it really worth paying double taxes? Are there other aspects I'm missing?
