Self-exploitation is an ideological control mechanism of the bourgeoisie in modern capitalism, where, instead of outright coercion, more insidious mechanisms are used to extract surplus value from labor.

By activating the worker's will to generate value and "empowering" them to partake in "hustle culture", they create a system in which they can seize surplus value while the subject isn't even aware of their own exploitation. (your comments are a prime example :))

See also the Gramscian notion of cultural hegemony for more details on the mechanisms at play here.

We aren't against social justice here.
