> Throughout my time abroad, a common trend is that expats (note: first use of that word) don’t bother to learn local language and are typically unhappy.

In Switzerland, that's no longer going to be an option. They recently implemented a change that requires you to learn at least A1 level (super basic) German in order to keep your B-permit.

As a recent arrival on a B-permit, I think it's a good idea.
