Yes, the Master is willfully ignorant of the work it takes, and everything involved in producing food. If they had to tend for themselves, they would not be able to survive, so they are the dependent self-consciousness (not the Slave). And the key is the Slave’s labor. This is what Marx and Engels pick up on and magnify. For Marx, the meaning of life is found in and through one’s labor. Meaningful work is the existential key to fulfillment and meaning. A Master who does not work leads a shallow, meaningless life that depends on them remaining ignorant.
The figure of the Master is everywhere in film, literature, and indeed, in society. I don’t know the references you make to film above, but I’m thinking of _Bonfire of the Vanities_ by Tom Wolf (which was turned into a great film), and Bret Easton Ellis work — any of his novels that have also been turned into films, like _American Psycho_. In American psycho, you have the figure of Patrick Bateman, a man of privilege working in the financial industry and a psychopath. For me, Bateman is an example par excellence of the devolution of a Master consciousness.
