Eh, that's not a unique set of strengths. In any European country I know about (at least a dozen) you can get all-English education from kindergarten to PhD. In some for free, in some that's paid, but probably not as expensive as in the US. Everything is really rather a matter of tradeoffs and bang-for-the buck rather than categorical differences. Some European passports offer more access, but without the downsides of the US one. The only matter in which I don't know how to compare is the racial issues, but I hear the US is not exactly free of those either.
I dunno - I'm in Berlin and my kids go to a private school for English education. I don't think somebody who couldn't afford it and wasn't a native English speaker would be getting English without parental effort before 4th grade.
Also in the area I'm in plenty of people don't speak English - I just went to an eye doctor and they didn't speak English although to be fair that's the first time it's happened to me in 2 years.
