Highly skilled jobs can absolutely be 'perform or be fired', because you're paying for a person's ability to do a specialized thing, and there's usually only so much specialized work to be done.
But there are also a lot of 'we need bodies at a low cost' jobs.
And those latter jobs run on work_output : labor_cost, which can always be maximized by making fewer workers do more.
(Consequently, why the real goal for people studying / graduating in the modern economy should be to find a way to get into the former jobs...)
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.
