I've only taken a recent interest in history (specifically labor), but if you look at the grand scale of either direct physical enslavement or designed econeomical indirect enslavement (surfs to their rulers), you find so much of history dating back to the Egyptian empire of kingdoms that relied their econemy in significant part with labor enforcement. You could try to argue about the right of withdrawing label just in context to American history, but I think we'd still wind up with a compelling case that so much of history had periods of significant unjust-by-most-standards labor compulsion.
