Oh, absolutely - the posh European people I know (not truly posh, in a European sense as there are so many minor/ex royals knocking around - my circle of acquaintance peaks at senior diplomat sort of level) all speak 3 or 4 languages perfectly, and all send their kids off to school for at least a year, maybe longer, to here, the US and probably another fashionable place too, as well as having university terms or longer in different countries). What is somewhat hilarious though is that they generally assume I am posher than some of my truly posh colleagues because of my cultural capital. They don't get that I'm...you know. Not One of Us. They get that I play instruments to a high level, know about the music environment in their countries, know about history and theatre, literature, art etc. I was in Prague a while ago for work, in the company of many colleagues from different countries and I idly wondered out loud if one of the windows in the buildings we were passing was the famous one. My British, minor public school educated, very snotty, colleague looked blank and asked me to explain. The others were all shocked. 
There are many things that any properly educated person should know. Few of which involve brains intelligence or other skills, to be honest. As our schools transition from cathedrals of learning to training boot camps for quite possibly low level mundane drone work, these things are being gradually (maybe not so gradually actually) lost. To all but the monied. IME state schools are very strong on morals and that sort of thing. But they are in danger of becoming weaker in the things that make life worth living (because that's Gove's vision). I think some posh schools are going the same way too, but it's cold comfort.
