Good points. It does make me wonder, though, what would happen if everyone simply began refusing to do meaningless work. Would the world grind to a halt? I doubt it. I bet we'd eventually figure out how to reorganize things.
You know, there's a wonderful line from the Gospel of Thomas (one of the Gnostic texts which were originally rejected by the church and then dug out of the desert 60 years ago) in which Jesus' disciples ask him, "What must we do to be saved?" and he answers "Do not tell lies and do not do what you hate."
