Well the other large advantage is that the US is one single market with one common language (English) and while there are variations by state, pretty much one set of rules. So by starting a company in the United States you of course have access to incredibly deep capital markets, but you also have access to 350 million people mostly operating under one set of rules with one common language and largely one common culture. It's the same market advantage that China has, by and large.

It's one of the big ironies of the EU - every time it gets larger (good! increases market size) it also gets more fragmented in terms of languages, retained local rules etc. (bad, obviously).

Now up to 24 official languages and still potentially growing in the future (although this is a bit of an overcount because some of them are mutually intelligible to various degrees, it's still a lot).

It's interesting to think that at the time of original ECSC treaty there were only four languages (French, German, Dutch and Italian). That's just about manageable, now it is a bit of an issue
