It is this aspect which explains the great wave of discontent with slavery of the 6th century BC, which was not intended to free all slaves but only those enslaved by debt.
Upravo ovaj aspekt objašnjava veliki val nezadovoljstva ropstvom u 6. stoljeću pp. n.e., čiji cilj nije bio oslobađanje svih robova, nego samo onih koji su zbog dugova pretvoreni u robove.
