vocational training is training for work or labor; it is specialized rather than general; it is for an extrinsic end; and ultimately it is the education of slaves or workers. And from my point of view it makes no difference whether you say slaves or workers, for you mean that the worker is a man who does nothing but work -- a state of affairs which has obtained, by the way, during the whole industrial period, from its beginning almost to our day.
