The fact of the massive advantage that the US gives to companies and researchers in the form of essentially a single regulatory zone and, importantly, a single language, is reflected in the fact that almost all of the technology you are using was designed in the US. Google, Apple, Facebook, Microsoft, Amazon, etc. for companies, C, Python, Lisp, etc. just in programming languages... You only have to write documentation once for more potential customers or research collaborators to be able to read it than if you wrote in both French and German. This is well studied. Note that in terms of developed countries the US is the largest by far.
