Who is John Galt?

John Galt's speach from Altas Shrugged is a long, but very good, exposition about the immoralality of forcing other people to provide for your wants (socialism) or trade your mind for the comfort of an invisible friend (religion). I think it would be good to listen to it in full, but of course if you are a rational being that is actually your choice alone. If not, then my god is bigger and hairier than yours and will smite you hard if you don't.
