Yes, and this dichotomy has been analyzed by political and economic theorists for centuries and everyone except autocrats and slave owners has agreed that the conditions surrounding the "work_output : labor_cost" jobs you describe are a huge miscarriage of justice and ought to be discarded with the past. Whether that is predicted to occur via bloody revolution or capitalist accelerationism is a matter of your particular economic and philosophical taste. But every ethical human being says we shouldn't treat people like that.
