I think that in this song the speaker is someone who is single and is trying to talk a girl who is tied down into freeing herself. He says that we're born to multiply, talks about how she wants one more Saturday, etc. Then he talks about how she's tied down and has to pine through windowpanes and about how she's kidding herself thinking things are still fun being beholden to someone else. Even though he's trying to convince her to join the ranks of the free though, he's doesn't seem so sure himself if his way of life is better; he may be the one kidding himself and might really feel like he's of a dying breed as he gets older and all the other people around him start settling down. His motives for trying to convince the girl to free herself from her relationship with an ordinary joe may actually be selfish; he wants her to be "free", but "free" with him.
