To me this song seems to be about despair. "lose some sleep and say you tried" meaning a half-assed effort for trying to change, (yourself, the world, society, etc..) and demonstrating how "losing sleep" and worrying about something gives us just enough of a good conscience so that we can relieve ourselves of guilt without really doing anything to change it. We consider ourselves to be "good people" because we worried about something, which means that we care, which is more than most people do, so we are better than the rest of society, so now we can sleep easy knowing that we are better/good.
