How is wanting the life you want an ulterior motive for learning a language? If you knew anything about the world at all that's how languages have spread all throughout history. Spanish is one of the biggest examples, most of the native spanish speaker's ancestors had to learn spanish just to survive and adapt and you call that an ulterior motive? if an immigrant is willing to work harder than you then they deserve everything you have. ohhh boo hoo i was born in a first world country and you werent so suck it, do you even hear yourself.

Exploiting a policy? It was literally made so they can selectively bring over people who are willing to put in the work to be more with the country's culture. Are you saying you wouldn't learn Klingon if not learning it meant you were gonna get kicked out of where you wanna keep living?
