I watched this video awhile back, and didn't see a thread on it here except for one in the welcome section two years ago. It's an interesting analysis of how language, specifically the way language conveys the future, influences savings rate in a significant way.
Essentially, people whose languages make the future a discreet time separate from the present tend to save less than people whose languages don't differentiate between the future and present. They also tend to smoke less, use contraceptives more, and generally do things better for their future.
My girlfriend speaks Chinese and English, so this was especially interesting for her. His first point about naming of relatives is something I've directly learned being around her family, and is another interesting language component that is something that's just fundamentally different about the languages. It's easier to understand now how "____ doesn't really translate" can be true, language is far more complex than just ___ means ___.
