Precisely because everyone else does learn English we should be learning other languages.
Foreigners will go on learning English, regardless. The British have an obligation, it seems to me, to reciprocate. Call it what you like – mutuality, courtesy, fair exchange, good practice. Not to do so is in every sense hateful. A self-exemption. A trusting in force and market, where – for once – force and market do not apply. A departure from international polity. A terminal and blazingly wrong conceit.
Something to do with us being the polite ones perhaps?
