This song has a very deep meaning. They are basically saying to measure your life in love, and nothing else, not money, fame, clothes, material goods, nothing else matters. They are saying that they would rather lead a life full of love than one filled with material goods that have no meaning. This group of friends are bohemians living in the slums of New York, surviving on love and each other alone, but the fact that they don't have enough money to pay the rent is not relevant because they have love, and that's all that matters. My dance compay did a rent production, but that was before I saw the movie or the play, so I didn't understand the depth and meaning of the story. I wish I had.
