I think the song is narrated by both a prostitute, and someone who is hiring a prostitute and it's just a matter of perspective. More or less all the lines can be seen from either perspective, and the point of the song is simply that no matter your position in life, you'll always have problems. The rich man has too much money and tries and fails to buy love because he's lonely and dejected. The poor man can't feed his family so he has to sell his body to survive.
