> It doesn't really matter about the UK's status. Nobody is saying "well I live in a hegemon, I won't bother learning another language".
That's a straw man.
> For the most part, people learn languages because they are useful.
Duh. But how useful learning a new language is to you is mediated by where you're living and it's local influence. As an American, I would have to go way out of my way in order to use a new language, let alone find it useful. This is largely due to the cultural and economic weight that America exerts on the region. Literally everyone I've done business with who isn't a native English speaker taught themselves English specifically to move to or do business with Americans. The UK is not in this position.
Also, again, size. I have to travel a very long way before I hit anywhere where English is not the overwhelming majority language. This also is a factor. If I want to learn French and use it, it's a $600 and 14hr flight for me to actually make it to Paris and use it, while a Eurostar ticket from London is $60 and 2hrs. This absolutely affects how useful a new language might be, even for pleasure, and is exactly why my attempts to learn French petered out.
> I'm happy enough with that because speaking another language well represents thousands of hours of effort that I was happy to spend elsewhere - it is a huge opportunity cost.
If learning a language was useful to people in the UK, they would do it. I don't know why you are saying that people in the UK are not in the same position - they evidently are, which is why few bother learning languages. If what you say were true, it would be reflected by reality.
In fact, although the UK is near other countries in Europe where speaking non-English languages is common, anybody who travels anywhere in Europe will find that everybody speaks English. If you are in the UK and want to do business with anybody across the EU - they're going to speak English. If you want to learn any materials for any speciality - it will be available in English.
The majority of people in the UK go through their whole life without ever having to communicate with people who don't speak English. That includes the odd week they might spend on holiday in France or Spain.
So people in the UK are in much the same position as those in the US. There is no economic incentive to learn a foreign language. That's 95% of the motivation to do so, completely gone.
That's a straw man.

YMMV.
