Friedrich EngelsCompetition permits the capitalist to deduct from the price of labour power that which the family earns from its own little garden or field; the workers are compelled to accept any piece wages offered to them, because otherwise they would get nothing at all, and they could not live from the products of their small-scale agriculture alone, and because, on the other hand, it is just this agriculture and landownership which chains them to the spot and prevents them from looking around for other employment.
