IIRC Singapore and a bunch of other high tech SE Asian countries essentially did the same thing. Anybody with a high tech qualification, eg a CS degree, could live and work in any of the club no questions asked.
France is pretty nationalistic too, no? They're one of the harshest countries in Europe in terms of minority languages, if I recall correctly.

Their attitude to the language rather shows that - nobody in England thinks English needs 'protecting'.
It shows in their proliferation patterns too.
Other languages borrow foreign words - English lures them into dark alleys and goes through their pockets for any grammer they might have.
The problem with defending the purity of the English language is that English is about as pure as a cribhouse whore. We don't just borrow words; on occasion, English has pursued other languages down alleyways to beat them unconscious and riffle [sic] their pockets for new vocabulary.
