"There is always the wish that the smallest possible portion of society should be doomed to the slavery of labour, to forced labour. This is the utmost that can be accomplished from the capitalist standpoint....."

"It is self-evident that if labour-time is reduced to a normal length and, furthermore, labour is no longer performed for someone else, but for myself, and, at the same time, the social contradictions between master and men, etc., being abolished, it acquires a quite different, a free character, it becomes real social labour, and finally the basis of disposable time—the labour of a man who has also disposable time, must be of a much higher quality than that of the beast of burden"
