The economics of learning languages

There is a kind of conversation which sounds intelligent, and which makes sense at first hearing, but which deeper thought reveals to be stupid. A classic example of this is the dinner party trope where some poncy polyglot belittles the British or Americans for being terrible at learning foreign languages.

The raw facts seem to bear this out. But further consideration reveals a reason behind this discrepancy. Seen through the lens of time, it is much harder to learn a foreign language if your first language is English than if it isn’t. How so?

Well let’s imagine how a Swede, say, might approach the issue: 1. ‘Do I need to learn another language?’ 2. ‘What language should I learn first?’ Easy answers. 1. ‘Yes’ and 2. ‘English’. Swedes need English not only to speak to English people, but even to speak to Danes or Finns — to swap herring recipes, perhaps, or to coordinate their shameless reciprocal voting tactics for the next Eurovision Song Contest.
