There is definitely something to your idea. I have moved countries a couple of times in recent years and found that I get fewer opportunities to use the local language than in past moves, simply because a lot of face-to-face interaction has been replaced with online interfaces (the bank, state offices) or automated kiosks. And I am the motivated, educated immigrant with plenty of time to spare who wants to learn the language and absorb all the idioms and local culture references expressed in it.
