In the famous Boonta Eve podrace from Star Wars: Episode I – The Phantom Menace, Sebulba taunts a young Anakin:
'You won't walk away from this one, you slave scum.'
To what extent is there truth in the "slave" part of this?
Were the Skywalkers, and all humans, slaves? Or is this just interplanetary trash talk?
My question is more about the origin of their slavehood, and slavery of humans, in general. Are there any hints that anyone ever hunted Anakin as a runaway slave?
