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.
