A clear boundary exists between the servile and the non-servile condition of labour, and the conditions upon either side of that boundary utterly differ one from another, Where there is compulsion applicable by positive law to men of a certain status, such compulsion enforced in the last resort by the powers at the disposal of the State, there is the institution of Slavery; and if that institution be sufficiently expanded the whole State may be said to repose upon a servile basis, and is a Servile State. (Hilaire Belloc)
