I think the song is about a guy having a crazy day and how he comes to realize what people have to do to survive. I think that he also realizes people have to do different things to survive as they are all different and they know how to exploit their skills such as the thug using his knowledge of guns, the con man using his knowledge to swindle money from the church and the prostitute using her feminine wilds. The main character realizes at the end that people only do what they do to survive and he almost forgives them for what they do.
