I also think that the UK will very much need people who are at home with how things are done in more civilised countries, have excellent language and communication skills, etc. As recent events have shown, we are too insular in this country.
Yet, ds, who has lived in Belgium since he was 10, chose to go to UK for university. He can get by in Flemish and French. He is currently doing his MA at the same place he did his BA...which is known for having a international cohort.
As for more civilised countries.....moot point. Those will be the ones where all the police are armed, and you can be fined for not having your ID papers/card on you? Mainland Europe does not equal more civilised at all ime and imo.
