A lot of people have misinterpreted this song as some sort of promotion of married life or the importance of finding a partner but it was never meant to be about romantic relationships.  It’s about being aware of the fact that the way we act now determines how life folds out in front of you.  Pick grasping and acquisition of wealth at the expense of others and ultimately you will be left with an empty existence, where as if you choose to be giving and strive to be a caring person you will most likely end up with genuine and meaningful relationships.  Basic karma really.
