What about cultural imperialism? A language shapes your identity because it literally gives the grammar to your thoughts. But other cultural goods like music, netflix, youtube, tv, you name it, do shape our cultural grammar just as much. This is a point I don't expect anyone already embedded in the dominant culture to find salient, because the culture we are in is as transparent as sea is to fish.
> People are begging to come to wealthy countries
If people had comparable prospects at home, so few would actually leave. If you look at the non-asylum-seeking immigration reasons (i.e. the "beggars" in your words), it is primarily about economic hardship, with persecution, violence, war, human rights added on top. Guess what, in an interconnected international arena, wealthy countries have more culpability about those conditions than we care to admit.
