That brings up an interesting question: in historical terms, the subject of this story is quite well-off; he's not always physically at risk, he has ready access to probably non-toxic food, he has shelter, etc. Over a long enough timeline, his life is pretty good. Even his home situation--mom is a prostitute, but he can't tell anyone lest the authorities separate them--is in all likelihood less common than it might have been centuries ago.
So if these conditions are so awful that we can't possibly expect people to improve without fixing said conditions, how do we explain historical economic growth. We're descended from people who had really miserable lives: sleep in a cave, hope you can hunt or gather enough food to stay alive, go to sleep hungry more often than not, risk death by infection every time you get a cut that's more than skin deep, and reproduce through what any modern person would call serial rape. Beings that were physiologically human (basically us, but probably lactose intolerant) had to deal with all of those circumstances, and managed to bequeath to the next generation some slightly less miserable circumstances.
It comes back to the anthropic principle: if misery is a strong disincentive for progress, how did we progress to the point that we have leisure time to discuss this?
(I've asked the same question on Quora here: http://www.quora.com/How-do-adherents-to-the-bee-sting-theor... . I am very interested in the answers.)
